Product Description:

The MAC025A-0-WS-2-E/040-A-1 belongs to the MAC AC Servo Motors series from Bosch Rexroth Indramat. It is a permanent-magnet synchronous motor built for integration with analog velocity and torque controllers in light-duty industrial axes. Inside production machinery, it translates amplifier commands into precisely controlled rotary motion. The motor also supplies feedback signals that help keep position loops stable and repeatable during operation.

Its electromagnetic circuit uses winding code WS, which sets the phase resistance and inductance needed for pairing with low-current analog drives. Heat is removed through natural convection, eliminating the need for external blowers and allowing installation in enclosed areas where airflow is limited. Rotor position and speed are reported through integrated tacho feedback, which provides the analog voltage required by legacy drive cards for real-time velocity monitoring. The motor has a frame size of 025 and a frame length of A. This compact arrangement suits pick-and-place heads and small indexing tables without adding unnecessary mass. The permanent-magnet rotor supports responsive acceleration, while synchronous operation allows the connected controller to regulate motion accurately under changing commands.

The housing includes a standard blocking brake that clamps the shaft whenever the control voltage is removed, helping hold vertical loads without external actuators. Power conductors exit through a connector on side A, simplifying cable routing where service space is limited on one side of the machine. As a motor for analog drives, the unit remains compatible with earlier Indramat supply modules and control equipment. Its integrated feedback allows the analog controller to detect speed changes quickly and adjust motor current in response to load variations. Natural heat dissipation also removes the maintenance requirements associated with external cooling fans, while the compact housing supports installation on small automated axes. The blocking brake provides shaft retention during power loss or planned stops when the connected load must remain stationary.
