Product Description:

The MAC063B-0-JS-4-C/095-A-1/WI522LV is a brushless AC servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed as a motor for analog drives, it converts command voltages from legacy controllers into precisely regulated shaft rotation for positioning and cyclic motion in industrial cells. In plant environments where axes must remain motionless between cycles, its standard integral blocking brake secures the shaft without relying on external clamping devices.

With a frame designation of 063 and a motor length code B, the unit occupies minimal space while still presenting a centering diameter of 95 mm for precise flange alignment. Shaft speed reaches 6000 min⁻¹ under nominal operating conditions, giving high dynamic range for indexing tasks in mid-range machining centers and high-speed packaging lines. The blocking brake supplies 3 Nm of static holding torque, which is sufficient to maintain position on moderate inertial loads. Heat is removed solely by natural convection, so installation must allow unobstructed airflow around the housing, and no auxiliary blower or liquid circuit is required.

Electrical characteristics are matched to winding code JS, and motion feedback is generated by a tachofeedback package that combines an incremental encoder with standard mounting and an auxiliary tacho generator. The tachometer delivers 1.5 V/1000 min⁻¹, giving analog velocity information to the drive, while the encoder furnishes digital position data for fine positioning. Power leads exit through a connector on side A, simplifying right-hand cable routing in compact cabinets. The incremental encoder arrangement provides repeatable home referencing without the added complexity of a multi-turn device, and overall signal quality is classified as standard tacho quality.
