Product Description:

The MAC071A-0-HS-4-C/095-A-0/WI520LV/S001 is a motor for analog drives produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for position or velocity control on automated axes where a command voltage from the drive amplifier must be translated into mechanical motion. The unit combines a 071 frame size with winding code HS so that it can deliver rated torque when supplied by legacy analog controllers used in older but still active production lines.

The motor is machined with a centering register of 95 mm, allowing accurate radial alignment against the mating flange. Heat is removed solely through natural convection, eliminating the need for forced-air ducts or liquid loops in compact cabinets. Under rated excitation, the rotor reaches 2000 rpm, and the tacho generator produces 3 V/1000 rpm, providing a linear speed signal to the analog drive. The HS winding code indicates the copper section and impedance so that the current demanded by the amplifier stays within its continuous rating. The feedback interface accepts either tacho feedback or an incremental or absolute encoder, enabling migration from pure velocity loops to full position loops without changing the mechanical package.

Mechanical coupling is through a DIN 6885 key seated in the shaft, while the overall frame is the compact 071 size so it fits directly in machines that previously held smaller MAC motors. Power leads exit through a connector on side A, simplifying cable routing in enclosures where adjacent axes sit in line. The motor is supplied without a blocking brake, an arrangement that reduces length code A and inertia yet requires the drive to hold position electrically when power is present. Standard tacho quality, incremental encoder mounting, and the natural-convection housing provide predictable performance for legacy production cells that still rely on analog velocity loops.
