Product Description:

The MAC071C-0-JS-4-C/095-B-0/WI634LX belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. This motor for analog drives converts electrical energy into controlled mechanical rotation for positioning or velocity-regulated axes in automated machinery. It is supplied without a blocking brake, so external measures must hold the load when power is off. Its housing uses passive cooling, which eliminates fans or liquid circuits and supports installation where simple ambient airflow is sufficient. This operating style suits compact machine sections that need dependable motion control without added cooling hardware.

The mechanical envelope centers on a flange with a 95 mm locating diameter that aligns the shaft to mating gearboxes or mounts. The frame designation 071 indicates the stator cross-section, while the construction length index C indicates the active stack depth used for the required torque. Under rated drive conditions, the rotor reaches a nominal speed of 2000 rpm, a value that fits many precision feed or traverse tasks. Heat produced at this operating point is removed through natural convection, so ambient airflow must remain unobstructed around the housing. Dynamic behavior is shaped by winding code JS, which sets coil resistance and inductance so that analog servo amplifiers can deliver current with stable phase margins.

The power leads exit through a connector on side B, which can simplify cable routing when the gearbox or driven load faces side A. Rotor position and velocity feedback follow the W arrangement, so the drive receives a tachogenerator signal of 3 V/1000 rpm along with pulses from an incremental encoder mounted in the standard interface. This combination gives the connected amplifier separate feedback signals for speed monitoring and position tracking during axis movement. Tacho quality is standard, which is suitable for speed loops that can tolerate minor ripple.
