Product Description:

The MAC071B-0-FS-4-C/095-B-0/WI522LV/S001 is manufactured by Bosch Rexroth Indramat and belongs to the MAC AC Servo Motors series. It is intended for analog drives where precise velocity and position control must be achieved through ±10 V command interfaces. Within an automation cell, the motor supplies rotary motion to axes that require rapid acceleration, and holding force must be provided by external drive torque or a mechanical lock when power is off. Its feedback arrangement allows the connected drive to compare commanded motion with actual motion and correct speed variations during operation. That makes it suitable for packaging equipment, transfer systems, and other machines that depend on stable low-speed regulation as well as repeatable positioning.

Mechanical mounting is centered by a 95 mm pilot on the flange, and torque is transmitted through a shaft machined with a DIN 6885 keyway. Heat is removed by natural convection, so the motor does not require a blower or liquid cooling loop. Power leads exit through a compact angled connector on side B, which helps keep cable routing clear of the driven load. Under continuous duty, the rotor reaches a nominal speed of 2000 rpm, a range that suits legacy drive inverters used on machine tools and handling stations. The keyed shaft also supports secure coupling to hubs, pulleys, or gearbox inputs that rely on positive torque transfer.

The motor uses winding code FS, which indicates resistance and inductance values matched to this design. Frame size 071 sets the housing size and inertia class, helping the unit deliver useful torque while keeping mass low for quick starts and stops. A built-in tachogenerator produces 3 V/1000 rpm, and this analog signal supports speed loops when the drive does not rely on digital feedback alone. For position tasks, the motor carries an incremental encoder with standard mounting, so the control system can monitor shaft rotation with repeatable pulse feedback. Using both feedback sources lets older control architectures separate speed regulation from position monitoring without adding an external feedback device. The B length keeps the housing short for compact gantries and other axes where installation space is limited, and the shorter body can reduce overhang on moving carriages.
