Product Description:

The MAC063A-0-ES-2-C/095-B-1/S001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Its frame size is coded 063, allowing the unit to fit compact mechanical spaces while supplying torque for analog velocity-control systems. The motor converts speed references from compatible drive amplifiers into controlled rotation for feed screws, pick-and-place heads, and small conveyor shafts in industrial automation. Its electromagnetic design supports dependable operation in older machinery and retrofit applications where digital feedback is unavailable.

A shaft-mounted blocking brake rated at 3 Nm prevents unintended motion whenever the control signal is disabled. A centering collar measuring 95 mm supports coaxial alignment with gearboxes, belt pulleys, and other driven components. Heat produced in the windings is removed by natural convection, eliminating the need for an external blower or liquid-cooling manifold. Rotor velocity is monitored through tacho feedback, which allows the drive to regulate speed without a separate encoder. The magnetic circuit supports a nominal operating speed of 3500 rpm, providing sufficient velocity for rapid traverses while remaining compatible with standard analog controllers. This arrangement also avoids the maintenance requirements associated with auxiliary cooling equipment.

Electrical power is supplied through a connector on side B, simplifying cable routing when the rear of the motor faces an access panel. The tacho generator has a calibration constant of 1.5 V/1000 rpm, producing a proportional voltage signal that compatible velocity modules can process. Stator copper and lamination geometry follow the ES winding code, matching the motor’s resistance and inductance to analog amplifiers capable of delivering the required current profile. The short length A housing keeps the motor’s mass and inertia low, supporting fast acceleration in light gantry drives and repetitive positioning axes. Its compact form also reduces the axial clearance needed between the motor and nearby machine components. Power and feedback connections remain accessible from the designated side, allowing the surrounding equipment to be arranged without obstructing the motor interface.
