Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI652LV/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Developed for analog servo amplifiers, the motor converts regulated current into precise rotary motion for indexing tables, pick-and-place heads, and compact packaging axes. Its stator and moderate rotor length provide favorable inertia for rapid speed changes without excessive overshoot. The compact housing also allows installation in machinery with limited mounting depth while supporting continuous-duty operation.

The motor dissipates heat through natural convection, so it does not require fans, ducts, or liquid channels. It has no blocking brake, which means drive torque or an external clamp must hold the load when power is removed. The motor has a frame size of 025 and a frame length of C. These characteristics provide the compact mechanical profile and magnetic stack used for this motor configuration. Power enters the winding through a connector on side B, keeping the motor leads toward the rear of the machine frame for orderly cable routing and convenient access.

Shaft position is monitored by an incremental encoder with standard mounting, which sends pulse trains and an index marker to the analog controller for speed regulation and homing. The housing also supports tacho feedback with an incremental or absolute encoder when the application requires additional position or velocity information. Classified as a motor for analog drives, the unit works with legacy ±10 V amplifiers rather than modern fieldbus inverters. The feedback arrangement allows the connected amplifier to monitor shaft movement and correct speed deviations during operation. Passive cooling reduces the number of auxiliary components around the motor, while the side-B connector helps keep wiring clear of nearby moving mechanisms. External load retention is necessary on vertical or gravity-loaded axes because the shaft is not secured by an integrated brake.
