The S-Series servo motors optimized for use with the S2K Series controllers range from

30 W to 5 kW and are rated for 230 VAC for full speed. Using a 115 VAC supply will result

in a reduced operating speed of approximately one half of the rated speed.

The 30 to 1.000 Watt S-Series servo motors (SLM models only), MTR-3S and MTR-3N

series and all stepping motor models are designed with standard NEMA shaft and flange

mounting configurations for easy mounting to off-the-shelf gear reducers and couplings.

The 750-Watt S-Series motor uses an oversized shaft diameter (0.625 inches) for the

NEMA 34 mounting in order to handle the peak torque rating of this model. 

S-Series motor models from 1 to 5 kW (except the SLM100 1kW motor) and all MTR-3T Series motors

have metric mounting configurations.

All servo motors are available with an optional 24 VDC holding brake. These brakes are

spring-set, electrically released models designed for holding stationary loads. The user

must supply a separate 24 VDC brake power supply. The 30-750 Watt S-Series motors

have a pigtail cable with box style connectors for motor power, encoder and brake

connections. The 1.000 to 5.000 Watt S-Series motors have MS style connectors and the

brake power (when required) is integrated with the motor power connections in a common

connector/cable. MTR-series servo motors include MS type connectors for brake power

input. The MTR-3N and MTR-3T series brake motors integrate the brake power with the

motor power in the same cable. MTR-3S brake motors require a separate brake power cable (CBL-30-BT).
