MAC AC Servo Motors
The MAC063B-0-GS-2-C/095-A-1/S020 is an AC servo motor delivered by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Intended for analogue drive amplifiers, the unit converts control signals into rapid and repeatable rotary motion within automated machinery. A standard blocking brake is integrated so the shaft remains fixed when the drive is powered down, preventing unintended movement during maintenance or load changes.
The brake produces a holding force of 3 Nm, adequate for light to medium loads found in indexing tables or small gantries. Alignment during installation is assisted by a centering pilot of 95 mm, which matches Rexroth flanges in this frame class. Heat is removed solely through natural convection; no external fan or coolant circuit is required, so cabinet airflow must be sufficient to handle continuous losses. Command feedback is supplied by an internal sensor stack with tachofeedback, allowing the analogue controller to measure speed directly and correct any deviation in real time. Under rated conditions the rotor reaches 3500 min⁻¹, a speed that balances dynamic response with the torque available from the GS winding set.
Electrical power is routed through a connector on side A, keeping cables clear of the driven load and simplifying service from the motor’s front face. The tachogenerator delivers 1.5 V/1000 min⁻¹, giving the drive a linear speed reference even at low rpm. With a frame code of 063 and a body length classified as B, the motor fits compact axes where space is limited yet inertia must be minimized. The electromagnetic profile is defined by winding code GS, ensuring current and voltage limits that match legacy analogue amplifiers.
