MD28-012-o

28mm Stepper Motor with Controller & Driver, 0.12 Nm, 24 V, Absolute Encoder, RS485

The MD28-o Family replaces PD-1021 Family* in our product portfolio.

The MocDrive MD28-012-o, part of the MD28-o Family, is a full mechatronic extremely small and compact solution with state of the art feature set. It includes a motion controller/driver using an outstanding technology for sensorless load dependent current control. This allows an energy efficient operation of an open-loop stepper motor system. Another advanced feature is to detect the load of the motor with high resolution.

The MD28-012-o includes a stepper motor, the IKS28-12E controller & driver electronics, and an absolute encoder. It can be used in many decentralized applications and has been designed for 0,06… 0,12 Nm max. holding torque and 24V DC nominal supply voltage. The MocOS firmware with serial protocoll allows for standalone operation and direct mode.

*PD-1021 Family: PD28-1-1021, PD28-3-1021
