Product Description:

The MAC025A-0-WS-2-E/040-D-1 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is supplied as a motor for analogue drives and is intended to deliver precise velocity and torque regulation in industrial automation where analog amplifier modules are still deployed. The housing relies on passive heat dissipation, so the unit can be mounted inside compact machinery without additional airflow hardware.

The electrical configuration is defined by the WS winding code, which sets the phase resistance and inductance so that analog current-loop amplifiers achieve their rated bandwidth without saturation. Thermal management is based on natural convection; heat travels from the stator laminations through the frame directly into the surrounding air, eliminating fan noise and reducing maintenance. Rotor position and speed are reported through tachofeedback, giving the drive an analog voltage that is proportional to shaft speed for closed-loop velocity control. Mechanical proportions follow a motor length 025 stack, providing a moderate magnetic path that balances continuous torque with a low moment of inertia. Frame envelope is dictated by motor size A, allowing the flange to mate with compact gearheads and couplings common in pick-and-place modules.

An integrated standard blocking brake engages automatically when power is removed, preventing vertical or overhung loads from back-driving the shaft during standby. Within the MAC AC Servo Motors series, this compact unit occupies the lower inertia category, making it suitable for fast index moves that demand rapid acceleration and deceleration. Alignment with Bosch Rexroth Indramat analog controller families keeps tachogenerator scaling consistent, so no external conditioning is required. As a motor for analogue drives, the device connects to legacy servo amplifiers through simple terminal blocks, preserving existing control architectures while upgrading mechanical performance.
