Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI673LV/S006 is an AC servo motor in the MAC AC Servo Motors series from Bosch Rexroth Indramat. Designed as a motor for analog drives, it receives regulated current from a compatible amplifier and converts that electrical energy into controlled rotary motion. The amplifier interprets ±10 V command signals used for position, velocity, or tension regulation and adjusts motor current accordingly. Integrated electrical feedback supports stable low-speed torque in automated conveyors, compact gantries, and process equipment that require precise electromechanical actuation.

The motor has a size 025 frame and a length C active stack, which provide a compact housing with useful continuous torque for moderate loads. Heat is released through natural convection, so the installation does not require an external blower or liquid-cooling circuit. Air must circulate around the housing to carry heat away from the stator during continuous operation. Power conductors terminate through a connector on side B, allowing cables to be routed away from nearby machine plates or moving components. Rotor position is monitored by an incremental encoder, enabling a compatible analog amplifier to regulate velocity and position through closed-loop control. The encoder supplies repeated position increments that the control electronics use to track shaft movement and respond to changes in load.

An internal tachogenerator supplies the required tacho feedback signal for analog velocity control. This signal varies with shaft speed, allowing the drive amplifier to correct deviations without relying solely on the incremental position channel. The motor is supplied without a blocking brake, so an external mechanical device or continuous drive torque must hold a stationary load when necessary. If electrical power is removed, the shaft can rotate unless the connected machine provides a separate holding mechanism. The sealed housing helps protect internal windings and feedback components from contaminants encountered in industrial machinery. Its winding characteristics and back electromotive force are suited to classic voltage-commanded amplifiers, helping the drive maintain controlled sinusoidal current during operation. Cable routing, available airflow, and external load retention should therefore be considered when the motor is installed in an automated axis.
