Product Description:

The MAC025A-0-WS-3-E/040-A-1/S001 is an AC servo motor built by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Integrated into closed-loop motion axes, it converts regulated current from a compatible drive into precise rotary output for positioning tables, pick-and-place heads, and light machining fixtures in automated equipment. Its compact design supports applications that require controlled torque, accurate speed regulation, and responsive movement within a limited installation area.

The motor is supplied with a standard blocking brake that secures the shaft whenever control power is removed, preventing drift on vertically loaded assemblies. Its electromagnetic circuit uses the WS winding code, which matches the coil resistance and inductance to compatible analog servo amplifiers so that current-loop performance remains stable. The motor has a size of 025 and a compact A length, reducing inertia while allowing direct coupling to small gearboxes or timing-belt pulleys. Thermal dissipation relies on natural convection, eliminating the need for an external blower and simplifying installation where forced airflow is undesirable. The compact housing and passive cooling method also reduce the number of auxiliary components needed around the motor.

Shaft position data is delivered through tacho feedback with a second shaft end. The integrated tachogenerator supplies real-time speed information to the drive, while the additional shaft stub can accommodate an optional encoder or mechanical load sensor. Power conductors terminate at a connector on side A, simplifying cable routing when the motor is mounted close to framing members or other machine components. Classified as a motor for analog drives, the unit pairs with compatible amplifier platforms that regulate velocity through voltage or current commands rather than digital fieldbus protocols. This arrangement allows the connected drive to monitor motor speed continuously and correct deviations caused by changing loads during positioning or velocity-controlled operation.
