Product Description:

The MAC090A-0-ZD-4-C/110-B-0/WI522LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for closed-loop motion axes that use analog velocity or current control, where the motor converts drive output into regulated torque for machine tools, packaging stations, and handling equipment. When paired with an external amplifier, it supports steady speed control and repeatable positioning during continuous production cycles. Its integrated feedback devices allow the drive to react quickly to load changes, which helps keep motion smooth during starts, stops, and speed changes. This arrangement is useful in equipment that needs predictable response during indexing, feed motions, and synchronized handling tasks.

A centering diameter of 110 mm allows accurate seating on standard mounting flanges and helps maintain alignment at the machine interface. Heat is removed through natural convection, so the installation should allow free airflow around the housing rather than rely on forced cooling. Because cooling is passive, there is no separate fan assembly on the motor housing. At its nominal speed of 1500 rpm, the motor supports continuous operation with a compatible drive. The ZD winding code indicates electrical characteristics suited to moderate base speeds and quick current response. The motor has no blocking brake, so any holding function at standstill must be supplied by the drive or external mechanics.

Electrical connections use a connector on side B, which can simplify cable routing when the motor is installed in line with adjacent machine components. Velocity feedback is supplied by a built-in tacho generator with an output of 3 V/1000 rpm, giving the analog drive a direct speed signal for regulation. Position data is provided by an incremental encoder, allowing the control system to monitor shaft movement during commanded motion. The combination of speed and position feedback supports stable regulation across a typical operating range. As a motor for analog drives, the unit is intended to operate with compatible Indramat amplifiers that issue proportional command signals without requiring extra interface modules.
