Product Description:
The MHD093C-058-PG1 is a servo motor produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. It functions as an electromechanical actuator in industrial automation, converting drive output into controlled rotation for indexing tables, pick-and-place modules, and packaging machinery. By combining permanent-magnet excitation with internal feedback, the motor provides precise velocity and position control required in multi-axis systems. Designed to operate with Rexroth digital drives, it fits installations where cabinet volume and thermal headroom are constrained, and it supports stable motion during frequent starts, stops, and direction changes.
At standstill, the motor can deliver 23.0 Nm of continuous torque, so thermal limits are not reached during static holding or low-speed creep. The mechanical interface uses a 140/150 mm square flange together with a 130 mm centering diameter, which helps align the housing on matching machine interfaces and supports accurate shaft positioning. Electrical behavior is tied to winding code 058, which sets phase resistance and inductance for use with compatible Rexroth drives. Rotor position is monitored through digital servo feedback generated by an integrated encoder, supplying high-resolution signals to the control loop and allowing the controller to correct motion errors quickly under changing loads.
The C-length frame incorporates a holding brake rated at 22.0 Nm. When power is removed, this electromagnetic clamp locks the rotor and secures vertical or suspended loads. Power is transmitted through a plain shaft, a style used for couplings that rely on friction or shrink-fit rather than keyed engagement. There is a shaft seal, so lubricant migration from the driven machine is limited and the entry of contaminants is reduced. Position information is stored as an absolute position covering more than 4096 revolutions, allowing immediate reference at startup without homing moves and supporting faster return to normal operation after a power cycle.
