Product Description:

The MAC025A-0-WS-4-E/040-B-1/WI673LV/S007 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The motor receives controlled current from a compatible drive amplifier and converts it into precise shaft torque and speed. Its low-inertia design supports coordinated motion in automated handling, assembly, and packaging cells. Accurate feedback helps the connected controller maintain repeatable positioning when loads and commanded speeds change.

The motor uses winding code WS, which sets the coil resistance and inductance for operation with compatible legacy ±10 V amplifiers. Its frame size is 025, providing a compact mechanical envelope for installations with limited space. The motor has an A length, which keeps the housing short while providing sufficient active material for its intended torque range. Thermal energy leaves the housing through natural convection, eliminating the need for a fan or separate liquid-cooling circuit. Adequate clearance around the housing allows ambient air to carry heat away during operation. Power conductors terminate at a connector on side B, allowing the harness to run toward the rear of the machine base. This connector position keeps the area near the shaft accessible for coupling hardware and simplifies cable routing around adjacent components.

Holding capability is provided by a standard blocking brake, which secures the shaft when the drive is disabled. This brake can prevent a stationary vertical load from drifting after motor torque is removed. Position feedback is generated by an incremental encoder with standard mounting, allowing compatible Rexroth encoder assemblies to attach without special shims or adapters. For systems that require additional velocity information or absolute position detection, the motor platform supports tacho feedback with an incremental or absolute encoder. As a motor for analog drives, the unit uses conventional voltage and tachometer signals rather than relying on high-speed fieldbus communication. This signal arrangement supports operation with older motion controllers that use direct analog command and feedback channels.
