Product Description:

The MAC090A-0-ZD-4-C/110-B-1/WJ534LX is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It converts electrical energy into controlled rotary motion for industrial automation tasks that require precise positioning and constant speed. Integrated into analog drive chains, the unit forms the electromechanical interface between a motion controller and the driven mechanical axis, supporting repeatable duty cycles in packaging, printing, and material-transfer equipment. The motor is intended for applications where the drive must translate analog command signals into smooth shaft motion with predictable response during continuous machine operation.

The motor’s machined centering flange measures 110 mm, ensuring concentric alignment with companion gearheads and minimizing radial runout. A nominal speed of 1500 rpm balances torque output with moderate inertia loads common in conveyor and indexing stations. Heat is removed by natural convection, so enclosure airflow or liquid circuits are unnecessary. Because cooling is passive, the housing can dissipate normal operating heat without an auxiliary blower. Main conductors terminate on a connector on side B, keeping service access clear of the shaft end. For closed-loop velocity control, the integrated tachogenerator supplies 3 V/1000 rpm, giving the amplifier a proportional speed signal for correction during load changes.

For load holding, the motor includes a standard blocking brake that applies mechanical restraint whenever drive power is removed. This is useful when the axis must remain in place during power-off intervals or controlled stops. The ZD winding code indicates phase resistance and inductance values matched to compatible Indramat analog amplifiers. The built-in feedback set offers a tacho feedback encoder, allowing incremental or absolute position data to be returned for supervisory monitoring without external sensors. As a motor for analog drives, it fits legacy control layouts while preserving MAC series mechanical dimensions, cabling geometry, and standard tacho quality used in mature motion systems.
