Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI654LV is a servo motor in the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. Designed for use with analog drive controllers, it delivers closed-loop rotary motion to transfer lines, pick-and-place stations, and other precision machine axes. The unit works with a separate drive that supplies motor current and receives feedback signals for accurate speed and torque regulation. It is suited to compact automated mechanisms where repeatable motion is more important than raw output size. Because the feedback loop is closed through the drive, the motor can respond predictably to changing loads during starts, stops, and short positioning moves.

Its mechanical form factor uses the C frame code together with the 025 length index, which gives a compact motor envelope for space-limited installations. Heat is removed through natural convection, so no auxiliary blowers or liquid circuits are required during operation. This cooling method also avoids fan maintenance and helps the motor fit enclosed machine sections where available space is limited. The motor is supplied without a blocking brake, which means holding torque must be provided by the drive or by an external locking device when the axis is stopped. Power connections are routed through a single connector on side B, and the arrangement helps keep cabling clear of adjacent moving components.

The electrical interface supports tacho feedback together with an incremental or absolute encoder channel for returning motion data to the controller. Shaft position is handled by an incremental encoder with standard mounting, which provides the differential signals needed for precise position interpolation. Because the unit is a motor for analog drives, it fits legacy control hardware that expects ±10 V command references instead of network-based communication. The returned signals allow the controller to monitor rotor movement during acceleration, steady-speed operation, and deceleration. This arrangement supports stable low-speed operation and coordinated motion where multiple axes must remain synchronized.
