Product Description:

The Bosch Rexroth Indramat MHD093A-058-PG0-AA belongs to the MHD Synchronous Motors series and serves as a servo actuator for industrial positioning stages, packaging equipment, and machining centers. It interfaces with compatible drives to deliver commanded speed and angle, enabling automated axes to follow CNC or PLC motion profiles with minimal following error during repeated production cycles. The plain output shaft, centering diameter, and power connector on side A simplify mechanical integration, while the absence of a holding brake suits applications that rely on drive torque or external clamps to secure load position during idle periods.

The motor can supply 12.0 Nm of continuous standstill torque, allowing it to hold a sustained load without overheating when the shaft is motionless. Its enclosure carries an IP65 rating, so dust ingress is prevented and water jets will not impair operation when the housing is properly sealed to the machine frame. Position and velocity are monitored through digital servo feedback with an integrated encoder, permitting high-resolution commutation and diagnostic data over the feedback channel. Mounting is performed on a square flange that measures 140 / 150 mm, providing a standardized bolt circle for direct attachment to gearboxes or couplings. Heat generated in the stator is dissipated by natural convection, removing the need for external blowers and allowing the motor to be placed where airflow is limited.

Thermal endurance is reinforced by insulation built to Class F, so the winding system tolerates internal temperatures up to 155 °C without degradation. Closed-loop positioning accuracy of the drive package is supported by a system error band of ± 0.5 angular minutes, helping keep cumulative backlash and quantization within tight machining tolerances in precision motion applications. The unit maintains continuous performance within an ambient range of 0 to 40 °C, and storage from −20 to 80 °C is acceptable when the motor is not in operation. The encoder provides absolute (>4096 revolutions) position detection, eliminating the need for homing moves after power loss.
