Product Description:

The MAC025C-0-QS-3-E/040-C-0 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, it converts drive current into precise rotary motion for positioning and velocity tasks in industrial automation. The unit uses the B05 mounting style and routes its power lead on side A. A second shaft end is fitted, and the integrated tacho supplies speed feedback to the drive. The motor has no blocking brake, making it suitable for applications that already use external holding mechanisms.

The motor delivers a continuous torque of 0.90 Nm while drawing a continuous current of 7 A, allowing the power electronics to support steady-state loading. Thermal energy is removed through natural convection, which eliminates the need for a cooling fan but requires adequate space around the frame for airflow. The permitted duty cycle is 25 %, indicating that full-load operation is limited to one-quarter of each operating period to keep the winding temperature within its allowable range. When high speed is required, the rotor can reach 10000 rpm, allowing the motor to support machinery that requires rapid acceleration and precise speed regulation.

Transient demands are handled by a peak current of 14 A, providing short bursts of torque without overstressing the stator windings. The maximum available torque is 3.47 Nm, which can help overcome static friction or accelerate loads during startup. With a rotor inertia of 0.41 kg cm², the motor responds quickly while limiting overshoot in lightly geared axes. At maximum torque, the shaft turns at 9190 rpm, allowing high mechanical output across most of the speed range. Torque at the absolute top speed is 2.40 Nm. The type code indicates a motor size of 025 and a frame length of C.
