Product Description:

The MAC025A-0-WS-3-E/040-B-1/S007 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It serves as a rotary actuator in analog drive systems that require precise speed and torque regulation. Typical applications include indexing tables, material-handling axes, and other automated equipment that uses controlled rotary motion. A compatible analog drive amplifier regulates the motor current in response to commands from the machine controller, allowing the shaft to follow changes in speed and load.

The motor has a frame size of 025 and a frame length of A, creating a compact housing for installations with limited space. Its stator windings use the WS winding code, which corresponds to the resistance and inductance characteristics required by compatible analog amplifiers. This electrical arrangement allows the drive to regulate current without exceeding the operating limits of the motor windings. The motor is equipped with a standard blocking brake that clamps the shaft when power is removed, helping prevent vertical or suspended loads from drifting. Heat from the stator is dissipated through natural convection, so the housing transfers thermal energy to the surrounding air without a fan or liquid-cooling circuit.

The feedback arrangement includes tacho feedback and a second shaft end. The tachogenerator produces an analog velocity signal that allows the connected amplifier to detect changes in shaft speed and correct deviations during operation. The additional shaft end provides a mechanical interface for attaching a secondary encoder, handwheel, or other compatible accessory when the machine configuration requires one. Power conductors connect through a connector on side B, keeping the cable exit in a consistent position relative to the mounting face. This connector location can simplify cable routing and help keep conductors away from moving machine parts or areas exposed to coolant spray.
