Product Description:

The MAC021A-0-YS-2-E/032-B-0 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The unit converts commands from a compatible drive controller into regulated rotary motion for automated machinery. Its compact housing is suitable for pick-and-place axes, small coil feeders, and auxiliary stations with limited installation space. The motor’s responsive operation supports equipment that requires rapid acceleration and controlled speed changes during repetitive production cycles.

The motor has no blocking brake, so external clamping or maintained motor torque must secure the connected load when power is removed. Omitting the brake reduces the mass and inertia added to the rotor assembly. Heat generated in the stator escapes through natural convection, requiring unobstructed airflow around the housing rather than forced-air cooling. Rotor velocity is monitored through tachofeedback, which supplies an analog speed signal to the connected controller. The motor has a short frame length of A and a frame size of 021. These dimensions correspond to a compact lamination stack and flange pattern intended for smaller automation axes while providing the mounting geometry needed for accurate alignment.

The main power supply reaches the motor through a connector on side B, allowing the cable harness to approach the housing from that face. This orientation can simplify cable routing when nearby machine components limit access to other sides of the motor. The electrical connection should be installed with sufficient clearance to avoid excessive cable bending and mechanical strain at the connector. The unit is a motor for analog drives and is compatible with voltage-controlled MAC servo amplifiers rather than digital fieldbus equipment. Its analog control arrangement allows the drive to regulate velocity or current using the motor’s electrical response and returned speed signal.
