Product Description:

The MAC025C-0-QS-4-E/040-A-1/WI671LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for analog closed-loop drive axes that require dependable torque and velocity regulation in pick-and-place units, textile frames, or compact conveyors. By converting electrical commands from analog amplifiers into mechanical rotation, the motor allows automated equipment to maintain repeatable positioning and stable speed under variable load conditions.

Heat generated by the stator windings is removed through natural convection, so no external blower or liquid cooling circuit is required. Sufficient clearance around the housing allows air to circulate and carry heat away from the motor surface. Power lines enter through a right-angle connector on side A, simplifying cable routing along adjacent machine walls. The motor has a frame size of 025 and a frame length of C, providing a compact housing for applications with limited installation space. Shaft angle is monitored by an incremental encoder with standard mounting, which delivers phased square-wave signals compatible with conventional analog drive cards for velocity and position control.

A standard blocking brake clamps the shaft when the drive disables torque, helping prevent uncommanded movement on vertical or overhung loads. This holding function can secure the connected mechanism during a controlled stop or while the drive is not producing motor torque. The motor supports tacho feedback with an incremental or absolute encoder, allowing the drive system to process speed or position information according to the installed feedback arrangement. As a motor for analog drives, it works with legacy transconductance amplifiers used in established production lines. Its compact format and right-angle power connection support installation in machinery where cable clearance and motor envelope are restricted.
