Product Description:

The MAC025A-0-WS-3-E/040-B-0/S001 is a compact AC servo motor produced by Bosch Rexroth Indramat and supplied in the MAC AC Servo Motors series. It is built for analog velocity or current controllers, where it converts ±10 V commands into controlled rotary motion for pick-and-place arms, indexing tables, and auxiliary axes on packaging or printing equipment. The motor’s construction emphasizes compatibility with legacy drive electronics while maintaining the durability required for continuous industrial duty cycles. This makes it suitable for machines that still rely on established analog control architecture rather than newer digital platforms.

The electromagnetic design uses winding code WS, which sets the nominal voltage, resistance, and inductance for matching analog amplifiers in its torque range. Heat is removed solely through natural convection, so the installation must provide free air circulation instead of forced cooling. Because the motor has no blocking brake, any holding torque during power-off conditions must come from external clamps or drive excitation. Mains power reaches the stator through a connector on side B, which helps keep cable routing orderly along the machine frame. The active magnetic stack corresponds to length class 025, keeping the body short while still supporting the continuous torque expected from this frame size.

The square frame is size A, allowing direct mounting to gearheads or machine plates drilled for the standard MAC pilot diameter. Speed feedback is derived from integrated tachometer feedback, which provides the drive with a proportional speed signal during operation. The design also includes a second shaft end, so an auxiliary encoder, pulley, or handwheel can be attached without an added coupling stage. Classified as a motor for analog drives, the unit fits existing motion systems that use traditional closed-loop speed control. This arrangement supports retrofit applications where the surrounding controller hardware remains in service. It also helps preserve familiar machine behavior on established production equipment.
