MD28-012-o

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

The MD42-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 is highly integrated and offers a convenient handling.

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. With the advanced stallGuard2™ feature the load of the motor can be detected with high resolution. With its high energy efficiency from CoolStep™ technology cost for power consumption is kept down. The MocOS firmware with TMCL emulation allows for standalone operation and direct mode.

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