Product Description:

The MAC025B-0-ZS-3-E/040-A-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat and included in the MAC AC Servo Motors series. Intended for use on analog servo amplifiers, the unit transforms current-command signals into tightly controlled shaft rotation for automated positioning, feed-axis regulation, and tool manipulation. Its frame is intended for compact machines where space behind the mounting flange is limited, and its mechanical interface allows straightforward coupling to gearboxes, timing pulleys, or direct-drive loads without additional adapters. Within a multi-axis rack, the motor occupies a narrow footprint while still providing full feedback connectivity.

Dimensional identifiers govern its continuous output capability. The frame code B sets the flange and pilot diameter, while the stack length index 025 establishes the magnetic depth and sustained torque at rated current. Thermal dissipation relies on natural convection, so the housing fins must remain clear of obstructions to keep winding temperature within the insulation class. Incoming three-phase power is routed through a sealed connector on side A, which helps reduce cable crossover when several axes are arranged in parallel. Rotor velocity information is returned by tacho feedback, an analog signal that the drive uses directly for speed control without digital interpolation.

Safety and integration characteristics round out the description. The motor is supplied without a parking brake, so a mechanical clamp on the load side may be necessary on vertical axes where the load could back-drive the system when power is removed. A machined second shaft end is available for auxiliary encoders, handwheels, or safety tachometers that need a direct mechanical link to the rotor. Classified as a motor for analog drives, the model remains compatible with legacy transconductance amplifiers while offering the mechanical and thermal standards expected of contemporary servo equipment.
