Product Description:

The MAC041B-0-BS-2-E/050-A-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat in the MAC AC Servo Motors series. It is intended for analog velocity and torque control, where a compatible drive converts command signals into precise rotary motion for positioning tables, feed axes, and light pick-and-place equipment. In automated equipment, that operating style supports steady speed regulation during light to medium duty cycles and short positioning moves. The motor uses a 50 mm rotor core, which helps balance output torque with low inertia for responsive indexing in compact machinery. Its compact mechanical format also helps preserve axis acceleration when moving smaller loads.

The motor is supplied without a blocking brake, so any holding force at standstill must come from external clamping or drive torque. Cooling is handled by natural convection, which removes heat without a fan and keeps the installation simpler in enclosed machine spaces with adequate air paths. This cooling method also avoids fan maintenance and added electrical demand. Integrated tacho feedback provides an analog signal proportional to shaft speed, allowing classic controllers to close the velocity loop without adding a separate feedback device. The motor has frame size 041 and a compact B length, which helps it fit small gearboxes or timing-belt drives where mounting space is limited.

Power is introduced through a shielded connector on side A, which keeps the main cable exit at the drive end of the motor and can simplify routing along a machine base or inside a cabinet. This arrangement can be helpful when cable movement must be minimized near moving carriages or guarded machine sections. Classified as a motor for analog drives, the unit works with voltage-controlled amplifiers commonly found in established automation systems. It also suits retrofit applications where existing analog amplifier hardware remains in service. The cable orientation leaves more open space around the motor body for nearby couplings, covers, or belt guards.
