Brushless servo motors SMH / SMB
Accessories and Options
Options
Parker SMH / SMB family motors are available with standard and custom options to adapt motor on your application.
If the option for your application is not listed, please consult our technical department.
Holding Brake
All SMH / SMB motors are available with option holding brake.
The fail-safe (supply voltage 24 VDC ±10 %) holding brake is incorporated in the motor at the opposite side of the front
flange (SM_170 front side) and is applied when there is no voltage present. Because of the power loss caused by the
brake, torque values must be reduced by 5 %. The holding brakes shall be used with the motor at a standstill and not for
dynamic braking. For maintenance, please refer to technical manual

Feedback
Motors may be eqquiped with various feedback types in order to meet the different requirements for precision, signal
that the application needs. The standard motor includes the resolver feedback. Hiperface Encoder, DSL Encoder, EnDat
Encoder, Incremental Encoder are available like the following tables.
