Product Description:

The MAC090B-0-PD-1-B/110-A-0-101000 is a three-phase AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for integration into analog velocity or torque loops, the unit converts drive commands into precise shaft movement for pick-and-place gantries, indexing tables, and web tension systems. Its compact frame, high dynamic response, and regulated feedback enable accurate positioning that supports consistent product quality on automated production lines. Because feedback signals are generated inside the motor, the external drive can correct speed changes quickly when load conditions shift during repetitive motion.

Mechanical interface dimensions start with a centering shoulder of 110 mm, which establishes radial alignment between the motor flange and the driven machine frame. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, balancing torque generation with thermal limits during continuous duty. Heat produced by copper and iron losses is removed through natural convection, so no external blower or liquid circuit is needed. Position and velocity are tracked by incremental encoder feedback, which delivers quadrature pulses for real-time loop closure in the external controller. For velocity verification, the built-in tacho generator supplies 3 V/1000 rpm, allowing analog drives to compare commanded and actual speed directly.

Power conductors exit through a connector on side A, which simplifies cable routing when the motor is mounted with the fan or gearbox facing the operator. Electromagnetic properties are set by the PD winding, which provides phase resistance and inductance suited to medium-voltage analog amplifiers. The shaft is held only by servo torque because the motor has no mechanical brake, which reduces inertial load during rapid reversals. Classified as a motor for analog drives, the unit is intended for MAC control platforms that modulate current through analog reference signals. This arrangement suits applications that need straightforward cable access and responsive motion without added brake mass. Axes that must remain fixed after power removal require an external holding method.
