Product Description:
The MAC041A-0-FS-4-E/050-B-1/WI670LV is an AC servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. The compact unit supplies precise torque and speed control to small machine axes, indexing tables, and pick-and-place actuators in automated production cells. When integrated with closed-loop drive electronics, it converts electrical setpoints into mechanical motion suitable for high-resolution positioning tasks in industrial automation. Its permanent-magnet rotor and sinusoidal commutation support smooth rotation at low speeds, allowing consistent product handling in assembly and electronics manufacturing lines.
The motor uses the FS winding, which establishes its voltage constant and continuous current capability for medium-inertia loads. Heat is removed through natural convection, so no external fan or liquid cooling circuit is required when the housing is mounted in free air. A blocking brake is mounted on the shaft to keep vertical or load-bearing axes stationary after power is removed. The motor has a size of 041 and a compact A length, resulting in a narrow housing that fits confined machine and gantry spaces. Adequate clearance around the housing allows rising air to carry heat away from the motor during operation.
The motor power conductors are routed through a connector on side B, simplifying cable runs in multi-axis assemblies. Velocity is monitored through tacho feedback, which provides an analog speed signal for the connected drive amplifier. Position sensing is supplied by an incremental encoder with standard mounting, which generates count pulses that the control system uses to track shaft movement. The motor is intended for analog drives and pairs with current-controlled amplifiers that accept tacho and encoder inputs without digital communication protocols. This feedback arrangement allows the amplifier to correct speed and position deviations as operating loads change. The side-mounted connection also helps route the motor cable away from the shaft coupling and adjacent moving components.
