Product Description:

The MAC025B-0-ZS-4-E/040-A-1/WI651LV is a compact AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for closed-loop motion axes in machine tools, handling robots, and packaging lines, the motor converts electrical commands from an analog servo amplifier into controlled torque and speed. This conversion supports precise positioning, regulated rotation, and repeatable movement under changing loads. The compact housing also allows the unit to fit into automation equipment where installation space is limited and controlled movement is required.

The housing has a compact B frame length, which keeps the motor short enough for installations with limited axial clearance. Its 025 frame size provides a small mechanical envelope that helps reduce motor mass and rotor inertia. Heat generated during continuous operation is removed through natural convection, eliminating the need for an external blower or liquid cooling circuit. Power conductors enter through a connector on side A, simplifying cable routing when that side of the motor faces the cable tray. The motor includes a standard blocking brake, which holds the shaft in position when control power is removed and helps prevent unintended movement on stationary axes.

Rotor position information is available through tacho feedback with incremental or absolute encoder support, allowing a compatible drive to receive the signals needed for velocity or position control. The installed measuring system is an incremental encoder with standard mounting, and its mounting arrangement aligns the encoder with the reference surfaces on the housing. The motor is designed as a motor for analog drives, so its windings and feedback signals are suited to classic Rexroth servo amplifiers. These amplifiers process the returned signals to regulate shaft speed, torque, and angular position during machine operation. Consistent connector coding, grounding points, and insulation materials support integration with compatible MAC motor cables and established analog drive systems.
