Product Description:

The MAC090B-0-PD-3-C/110-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat and part of the MAC AC Servo Motors series. Intended for positioning and velocity control in industrial automation, it works with Indramat drive amplifiers to deliver regulated torque to machinery such as index tables, printing lines, and packaging axes. The motor serves as the electromechanical element in closed-loop systems where stable feedback and predictable thermal behavior are important during continuous duty. This arrangement lets the amplifier correct for load changes during acceleration, deceleration, and steady-speed operation.

The motor is supplied without a blocking brake, so the shaft can rotate freely when the application does not require holding torque at standstill. A centering pilot of 110 mm matches standard flange patterns for accurate installation. Heat is removed through natural convection cooling, so no external blower is required. The rotor has a nominal speed of 1500 rpm, which suits gear ratios commonly used in medium-torque applications. Electrical power reaches the stator windings through a plug-in connector on side B, allowing cable routing to stay clear of the driven load or gearbox on the opposite face.

For velocity feedback, the rear extension carries tacho feedback with a second shaft end, which also allows coupling to an auxiliary encoder or mechanical sensor when needed by the machine layout. The integrated tacho generator delivers 3 V/1000 rpm, giving the drive controller a linear reference for speed regulation across the usable range. The electrical characteristics correspond to winding code PD, which matches the impedance and current limits expected by Indramat analog amplifiers during continuous operation. The unit is classified as a motor for analog drives, so it is intended for systems that use voltage-controlled drive electronics. The second shaft end can be useful where additional monitoring or auxiliary coupling is required without changing the main output arrangement.
