Product Description:

Bosch Rexroth Indramat builds the MAC063D-0-JS-3-C/095-A-0/S015 servo motor for the MAC AC Servo Motors series. Classified as a motor for analog drives, it turns reference voltages from legacy controllers into precise shaft motion for industrial robots, printing stations, and small machining centers. The design supports a second shaft end so auxiliary sensors or mechanical loads can be added without altering the primary coupling. This arrangement is useful in retrofit applications where modern encoders must share space with older tachometers.

A nominal speed of 3500 rpm is the continuous operating speed the rotor can sustain under rated current, giving the drive a high ceiling for closed-loop velocity profiles. The flange's 95 mm centering diameter positions the stator concentrically to gearboxes, which helps reduce radial misalignment at the mounting face. Thermal energy leaves the housing through natural convection, so the motor can be used in sealed cabinets as long as ambient air can circulate. Incoming three-phase power is routed through a connector on side A, keeping high-voltage leads on the service side of a machine. Winding code JS matches the impedance expected by MAC analog amplifiers and helps keep peak current within safe limits.

The motor has no blocking brake, so position holding during power loss must rely on external clamps or drive torque, and the omission also reduces added rotor inertia. Motion feedback comes from tacho feedback and a second shaft end, allowing the controller to monitor speed with an analog tacho while a secondary pulley or encoder uses the extra shaft stub. The tacho generates 1.5 V/1000 rpm, producing a linear signal that analog regulators can scale directly. The motor has length code D in frame size 063, giving it a compact housing for general automation duty.
