Product Description:

For industrial automation systems that require precise motion control, Bosch Rexroth Indramat has developed the MAC025A-0-WS-4-E/040-A-1/WI670LV Servo motor. Accurate adjustments in rotational force and velocity are achieved by combining permanent magnet design with adaptive feedback systems in this brushless AC servo motor.

The motor's highest torque production under low overloads is 1.27 Nm, with a continuous output of 0.60 Nm at full load. The space-saving design makes MAC025A-0-WS-4-E/040-A-1/WI670LV Servo motor compatible for direct attachment with robotic assembly and CNC operations machines. Embedded sensors in the stator keep an eye on the winding temperatures in real that ensures thermal protection. The optional electromagnetic brake provides 0.27 Nm holding torque for emergency stops, and the motor's aluminum enclosure fulfills IP65 specifications for dust and water protection. Even when operating at 90% load, the motor can maintain 5,990 RPM and provide 0.30 Nm of torque. Power efficiency during cyclic processes is achieved using a 0.2 kW DC bus draw. During periods of fast acceleration, the torque-speed curve remains stable with little variation across different loads.

With its maintenance-free design and sealed bearings that are pre-lubricated for prolonged service life, the MAC025A-0-WS-4-E/040-A-1/WI670LV Servo motor is compatible with incremental/absolute encoders. Its laminated rotor core minimizes cogging effects by optimizing the distribution of magnetic flux. Under continuous 1.2 kW DC bus operation, the speed parameters include a maximum limit of 10,000 RPM and a minimum limit of 7,220 min⁻¹. When connecting power lines and feedback devices, integrated cable glands keep ingress protection. For applications requiring high-precision positioning, the use of sophisticated sinusoidal commutation algorithms guarantees vibration-free rotation across the 10,000 RPM range.
