Product Description:

The MAC090C-1-GD-1-B/110-A-2/DI01250/S013 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages into controlled shaft motion for packaging lines, machine tools, and handling modules. When used with the proper feedback device, it supports closed-loop positioning and stable speed regulation on rotary axes. The design fits automated equipment that still uses analog control architecture while requiring repeatable and accurate motion.

The motor housing uses axial surface cooling, so an external blower moves air along the stator ribs to carry away heat during continuous operation. That blower operates on AC 230 V, so the installation requires a single-phase supply for the fan circuit. By directing airflow over the outer surface, this cooling method helps manage winding temperature without placing a fan inside the motor housing. A centering shoulder of 110 mm helps align the motor with the mounting flange and reduce mechanical runout. Winding code GD identifies the electrical winding used for this version. Power conductors exit through a connector on side A, which helps route cables toward the driven machine.

Axis holding is provided by a heavy-duty blocking brake, which keeps the shaft locked during power loss or on vertical loads. Position information is supplied through incremental encoder feedback for speed and position control in analog drive systems. The feedback device uses an incremental encoder with shock-damped mounting, which helps reduce vibration-related signal disturbance. The brake supports secure standstill behavior, while the encoder arrangement helps the drive respond cleanly to changes in speed and direction. This combination is well suited to equipment that operates with repeated starts, stops, and changing loads.
