Product Description:

The MAC071B-0-TS-3-C is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for closed-loop motion tasks, the unit converts drive commands into controlled torque and speed for positioning tables, packaging axes, and general machinery. When paired with an analog amplifier, this motor provides repeatable motion in industrial automation lines that require accurate velocity and position control. Its mechanical interface follows established Rexroth mounting dimensions, allowing alignment with gearboxes or belt transmissions used on production equipment.

Heat generated in operation is removed solely through natural convection, so airflow around the housing must remain unobstructed when the motor is installed. The rotor can reach a synchronous speed of 3000 rpm, giving medium-inertia loads rapid cycle times without exceeding thermal limits. Frame size 071 indicates a compact stator diameter for machines where space is restricted. The electromagnetic design is identified by winding code TS, which sets the phase resistance and inductance so the matched analog drive can deliver rated current. The tachogenerator output of 3 V/1000 rpm supplies proportional speed feedback for the drive regulator.

This model is categorized as a motor for analog drives, meaning its tacho feedback is intended for amplifiers that process continuous voltage signals rather than digital data. The feedback package is specified as with tacho feedback and a second shaft end; the extra shaft allows an external encoder or mechanical brake to be mounted without modifying the primary drive line. Motor length code B shows the stack height chosen to balance torque capability with envelope size. Tacho quality marked as standard confirms that the speed signal meets normal accuracy requirements for general-purpose automation.

Internal Product Review

  • ‘‘The MAC071B-0-TS-3-C is a motor for analogue drives with natural convection cooling. A 3000 min-1 nominal speed and tachofeedback with second shaft end support stable servo response and straightforward machine integration. Standard tacho quality with 3 V/1000 min-1 output makes signal handling especially predictable for analog control systems.’’
