Product Description:

The MAC071C-0-NS-3-C/095-A-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for integration into multi-axis machinery, the unit converts electrical commands from analog drive controllers into precise rotary motion for positioning, conveying, and synchronized process tasks. As a motor for analog drives, it depends on external electronics to supply current, monitor temperature, and enforce protective shutdowns. This arrangement supports repeatable motion on axes that need accurate speed regulation and responsive command tracking.

The motor has a frame size of 071, which matches common mounting flanges and the related stator diameter for this housing. A magnetic stack length of C increases active iron depth so the motor can deliver higher continuous torque without a larger frame. The rotor is centered in a 95 mm pilot, allowing accurate seating against gearbox or machine faces. Rated speed reaches 3000 rpm, giving a direct-drive option for applications that need moderate base velocity while retaining dynamic headroom. That speed range suits compact machine axes that require quick positioning and steady motion over a broad operating range. Electrical behavior is tied to winding designation NS, which identifies the phase resistance and inductance values used with matching analog amplifiers.

Thermal management relies on natural convection, so no external fan or liquid loop is required. This cooling method keeps the housing simple and avoids additional airflow hardware around the motor body. The motor has tacho feedback and a second shaft end, so it can provide a real-time speed signal while also allowing mechanical coupling for an encoder or brake if needed. Power enters through a connector on side A, which keeps cabling on one face of the machine frame. The tachogenerator outputs 3 V/1000 rpm, providing a linear reference for velocity loops, and there is no blocking brake.
