Product Description:

The MAC071C-0-US-3-C/095-A-2 is produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts command voltages from legacy controllers into mechanical rotation that positions or feeds industrial machinery in automated lines. Inside a motion axis, it serves as the electromechanical actuator and pairs with drive amplifiers that regulate current and velocity. This arrangement makes the motor suitable for equipment that depends on stable speed control and repeatable positioning during continuous production. In retrofit systems, this type of motor is often used where existing analog command structures are retained instead of being replaced with newer digital motion networks.

The motor size code identifies the frame as 071, while the motor length designation C indicates the active stack depth and supports the motor's continuous torque capability. A centering diameter of 95 mm aligns the housing precisely on gearboxes or mounting flanges. Heat is dissipated by natural convection, eliminating the need for forced-air components and simplifying cabinet layouts. Because cooling is passive, the housing can operate without separate fan maintenance or additional airflow hardware around the motor body. Stop-and-hold capability is provided by a heavy-duty blocking brake that delivers 6.5 Nm of static torque so vertical axes remain secure during a power loss. The brake circuit and power connection are routed toward side A, which helps keep cable entry consistent with common machine layouts.

The feedback package is supplied with tacho feedback and a second shaft end, giving both an analog velocity signal and an auxiliary mechanical interface for external encoders or load sensors. At its nominal speed of 2000 rpm, the motor produces a rated tacho output of 3 V/1000 rpm, which is easy to scale in analog control loops. The US winding code matches the electrical characteristics expected by compatible 230 V class amplifiers. The second shaft end can also support auxiliary sensing hardware when the main drive end is reserved for the machine load. That combination supports applications that need direct speed feedback while also leaving room for accessory coupling at the rear.
