Product Description:

The MAC063A-0-RS-2-C/095-A-1 is a servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for analog drive systems, the motor converts drive signals into controlled shaft rotation that maintains commanded speed and torque in automated assembly stations, packaging equipment, and light material-handling axes. Its integrated mechanical brake holds position when power is removed, while the built-in tachogenerator sends a velocity signal to the drive so closed-loop regulation can be achieved without separate feedback sensors.

Thermal energy is removed through natural convection, eliminating the need for external blowers in installations with adequate ambient airflow. The centering pilot of 95 mm aligns the housing precisely on machine mounting faces, which helps limit radial runout and supports consistent mounting. The motor has a nominal shaft speed of 6000 rpm, which is the normal continuous operating speed for this design. The tachogenerator produces 1.5 V/1000 rpm, giving the drive a linear voltage reference that scales directly with actual motor speed. During emergency stops or power loss, the blocking brake can resist up to 3 Nm of load torque, helping prevent unwanted back-driving of vertical or indexing axes.

The winding code RS indicates the coil resistance, inductance, and current constants used by companion analog amplifiers. Speed feedback is delivered through standard tacho feedback, which suits applications where absolute position is handled by external sensors. Power and feedback conductors exit through a connector on side A, allowing cable runs to follow the motor’s driven end and keeping bends to a minimum inside tight cabinets. Frame designation 063 sets the mechanical envelope, while length code A provides the shortest stack height in this series for installations with limited axial space.
