Product Description:

The MAC090B-0-PD-4-C/110-B-1 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. This model serves as a drive element in industrial automation where precise torque and speed control are required. By converting electrical input from analog drives into controlled mechanical rotation, the motor positions machine axes and maintains process accuracy in packaging, printing, and material-handling lines. It is intended for servo axes that must respond predictably to changing load conditions without losing commanded position.

A centering diameter of 110 mm establishes the reference fit against mounting surfaces and helps keep the shaft aligned with the driven load. Heat is removed through natural convection, so the housing must remain exposed to free airflow during operation. Under rated conditions, the rotor reaches 1500 rpm, which suits applications that need moderate base speed with steady running characteristics. Power connections are routed through a connector on side B, which can simplify cable routing when the rear of the motor faces the cabinet area. For holding the axis at standstill, the motor includes a standard blocking brake that applies retaining torque when supply power is removed.

Control feedback is supplied through tacho feedback with an incremental or absolute encoder, allowing the associated drive to regulate speed and position in closed-loop operation. The integrated tacho generator provides 3 V/1000 rpm, giving the controller a proportional speed signal for stable regulation across the normal operating range. The electromagnetic layout uses the PD winding, which matches the current and torque behavior intended for this motor size. This combination of feedback and winding data supports consistent response during indexing, speed holding, and general axis movement. The motor can be paired directly with proportional control amplifiers that are intended for this class of servo system.
