Technical definitions for main, linear and torque motors

Regulations, standards, specifications

SIMOTICS M-1PH8 motors (without brake), SIMOTICS M-1FE, SIMOTICS L-1FN3 and SIMOTICS T-1FW3 conform with the relevant standards and regulations.

For technical explanations of servomotors, see Technical definitions for servomotors.

As a result of the fact that in many countries the national regulations have been completely harmonized with the international IEC 60034-1 recommendation, there are no longer any differences with respect to coolant temperatures, temperature classes and temperature rise limits.

The marking is made on the nameplate or on a second nameplate.

Degrees of protection for three-phase motors

A suitable degree of protection must be selected depending on the operating and environmental conditions to protect the machine against:

• Ingress of water, dust and solid foreign objects
• Contact with rotating parts inside a motor
• Contact with live parts

Degrees of protection of electric motors are specified by a code. This comprises two identification letters, two digits and, if required, an additional identification letter.

IP (International Protection)
Identification letter designating the degree of protection against contact and the ingress of solid foreign bodies and water

0 to 6
1st digit designating the degree of touch protection and protection against ingress of solid foreign objects

0 to 8
2nd digit designating the degree of protection against the ingress of water (no protection against the ingress of oil)

W, S and M
Additional identification letters for special degrees of protection

Most motors are supplied with the following degrees of protection:
Motor	Degree of protection	1st digit Touch protection	Protection against foreign objects	2nd digit Protection against water
Internally cooled	IP23	Protection against finger contact	Protection against medium-sized, solid foreign objects with diameter above 12 mm (0.47 in)	Protection against spray water up to 60° from the vertical
Surface-cooled	IP54	Complete protection against accidental contact	Protection against damaging dust deposits	Splash water from any direction
	IP55			Jet water from any direction
	IP64	Complete protection against accidental contact	Protection against dust ingress	Splash water from any direction
	IP65 1)			Jet water from any direction
	IP67 1)			Motor under specified pressure and time conditions under water

¹⁾ DIN VDE 0530 Part 5 or EN 60034 Part 5 specifies that there are only 5 degrees of protection for the first digit code and 8 degrees of protection for the second digit code in relation to rotating electrical machinery. However, IP6 is included in DIN 40050, which generally applies to electrical equipment.

Recommended degrees of protection for three-phase motors

When cooling lubricants are used, protection against water alone is inadequate. The IP rating should only be considered as a guideline in this case. The motors may have to be protected by suitable covers. When selecting the motor degree of protection, the motor shaft must be equipped with a suitable seal.

The table can serve as a decision aid for selecting the required degree of protection for motors. It must be avoided that liquid accumulates on the flange when the motor is mounted with the shaft end facing upwards IM V3/IM V19/IM V6/IM V35.

Vibration severity and vibration severity grade A according to IEC 60034‑14 for SIMOTICS M‑1PH8 main motors

SIMOTICS M-1PH8 motors comply with vibration severity grade A according to EN 60034‑14 (IEC 600‑34‑14) as standard. The specified values refer only to the motor. The system vibration response depends on the conditions at the installation location and can result in higher vibration values at the motor.

As a general rule, high radial force load capacity is not compatible with high speed and high vibration quality. The reason for this is that the different applications require different bearings.

For SIMOTICS M-1PH8 motors, an acceptance test certificate with the actual measured vibration velocities can be ordered by specifying option B35.

G_PM21_XX_00185

Vibration severity limit values for shaft heights 20 to 132

The motors maintain vibration severity grade A up to rated speed.

G_PM21_XX_00186

Balancing according to ISO 8821 for SIMOTICS M‑1PH8 main motors

In addition to the balance quality of the motor, the vibration quality of motors with mounted belt pulleys and coupling is essentially determined by the balance quality of the mounted component.

If the motor and the mounted component are balanced separately before being assembled together, the balancing process of the belt pulley should be adapted to the balancing type of the motor. The following different balancing methods are used on motors of types SIMOTICS M-1PH8:

• Half-key balancing (an H is stamped on the shaft face)
• Full-key balancing (an F is stamped on the shaft face)
• Plain shaft end

In general, motors with a plain shaft are recommended for systems with the most stringent vibrational quality requirements. For full-key balanced motors, we recommend belt pulleys with two opposite keyways, but only one feather key in the shaft end.

Vibration stress, immitted vibration values for SIMOTICS M‑1PH8 main motors and SIMOTICS T‑1FW3 complete torque motors

The following maximum permissible limit value for vibration stress, but still retaining full functionality only applies to SIMOTICS T complete torque motors.

Motor protection for Pt1000 temperature sensor

The motor temperature is monitored using a Pt1000 temperature sensor integrated in the stator winding.

The Pt1000 has a linear thermal resistance characteristic. In addition, the Pt1000 has a low thermal capacity and good thermal contact with the motor winding (see characteristic).

Siemens converters calculate the motor temperature from the resistance of the temperature sensor.

The temperatures required for alarm and shutdown can be parameterized.

As standard, temperature sensors are evaluated in the SINAMICS S120 drive system.

Sensor Modules are used to evaluate the signals for SIMOTICS L-1FN3 and SIMOTICS T-1FW3:
SME120/SME125/TM120 (see SINAMICS S120 Equipment Manual).

If the motors are operated with converters that do not have a temperature sensor evaluation function, then the temperature can be evaluated using the external 3RS2600 temperature monitoring relay.

Paint finish for SIMOTICS M‑1PH8 main motors

Motors without a paint finish have an impregnated resin coating. Motors with primer have corrosion protection.

All motors can be painted over with commercially available paints. Up to 2 additional paint coats are permissible.

SIMOTICS L-1FN3/T-1FW6 motors have no paint finish, no coating and should also not be painted over

Built-in encoder

The encoder system is not included in the scope of supply of the SIMOTICS motor series M-1FE, M-1PH2, L-1FN and T-1FW6.

SIMOTICS M-1PH8 main motors and T-1FW3 complete torque motors can be ordered without encoders or with built-in encoders. For integrated encoder systems, a distinction can be made between an encoder with and without a DRIVE-CLiQ interface.

Built-in encoder systems without DRIVE-CLiQ interface

For motors without an integrated DRIVE-CLiQ interface, the analog encoder signal in the drive system is converted into a digital signal. For these motors and external encoders, the encoder signals must be connected to SINAMICS S120 via Sensor Modules.

Built-in encoder systems with DRIVE-CLiQ interface

For motors with integrated DRIVE-CLiQ interface, the analog encoder signal is internally converted into a digital signal. No further conversion of the encoder signal in the drive system is required. The motor-internal encoders are the same encoders that are used for motors without a DRIVE-CLiQ interface. Motors with a DRIVE-CLiQ interface simplify commissioning and diagnostics, for example, as the encoder system is identified automatically.

The different encoder types (incremental encoders, absolute encoders, or resolvers) are uniformly connected with one type of MOTION-CONNECT DRIVE-CLiQ cable.

Short designations for the encoder systems

The first letters of the short designation define the encoder type. This is followed by the resolution in signals per revolution if S/R is specified (for encoders without DRIVE-CLiQ interface) or in bits if DQ or DQI is specified (for encoders with DRIVE-CLiQ interface).

Multi-turn absolute encoder

This encoder outputs an absolute angular position between 0° and 360° in the specified resolution. An internal measuring gearbox enables it to differentiate 4096 revolutions.

For a ball screw, for example, the absolute position of the slide can be determined over a longer distance.

G_PM21_XX_00104

Multi-turn absolute encoder

Single-turn absolute encoder

This encoder outputs an absolute angular position between 0° and 360° in the specified resolution. In contrast to the multi-turn absolute encoder, it has no measuring gearbox and can therefore only supply the position value within one revolution. It does not have a traversing range.

Incremental encoder

This encoder senses relative movements and does not supply absolute position information. In combination with evaluation logic, a zero point can be determined using the integrated reference mark, which can be used to calculate the absolute position.

IC/IN incremental encoder (sin/cos)

The encoder outputs sine and cosine signals. These can be interpolated using evaluation logic (usually 2048 points) and the direction of rotation can be determined.

In the version with DRIVE-CLiQ interface, this evaluation logic is already integrated in the encoder.

Commutation position

The position of the rotor is required for commutation of a synchronous motor. Encoders with commutation position (also called C and D tracks) detect the angular position of the rotor.

Resolver

The number of sine and cosine periods per revolution corresponds to the number of pole pairs of the resolver. In the case of a 2-pole resolver, the evaluation electronics may output an additional zero pulse per encoder revolution. This zero pulse ensures a unique assignment of the position information in relation to an encoder revolution. A 2-pole resolver can therefore be used as a single-turn encoder.

2-pole resolvers can be used for motors with any number of poles. For multi-pole resolvers, the number of motor pole pairs and the resolver are always identical. so that the resolution is correspondingly higher than with 2-pole resolvers
