Custom shaft lengths and diameters are available on select SmartMotors. Flats and keyways are common options found on motor shafts. SmartMotors can be purchased with various versions of these shaft modifications.

Torque vs. Speed curve data is derived under dynamometer testing using a PS24V8A and PS42V20A power supply at an ambient temperature of 27°C (80.6°F).

External encoder input (including Mode Follow and Mode CAM) and RS485 communication is not available through ports E and F. Additional long term EEPROM variable data storage memory is optional.

Provisions for double shaft extension are standard; without the provision bore (back plate) is optional.

Connector kits and cable options are available.

SmartMotor servos have CE certification.
