Product Description:
The MAC025C-0-QS-4-E/040-B-1/WI670LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is intended for integration with analog drive amplifiers where precise speed and torque regulation are required for automated machinery such as small indexing tables, pick-and-place axes, and light-duty conveyors. The motor converts commanded current into controlled rotary motion, allowing the connected drive to regulate acceleration, operating speed, and holding position. Its permanent-magnet rotor supports responsive torque production in applications that require frequent starts, stops, and directional changes.
This model cools through natural convection, so ambient airflow removes heat without forced fans or liquid cooling circuits. A standard blocking brake is fitted to clamp the shaft when the drive is disabled and prevent load drift on vertical or suspended axes. The motor has a motor size of 025, which establishes the diameter and mounting dimensions used for this compact housing. Its frame length C provides the lamination stack depth needed to produce torque within the motor’s compact envelope. Power leads leave the housing through a connector on side B, allowing the cable bundle to remain clear of nearby moving components when the flange is attached to the machine. This connector orientation also supports orderly cable routing along the stationary side of an indexing table, conveyor, or positioning assembly.
Shaft position is monitored by an incremental encoder with standard mounting, and its quadrature signals support precise position tracking and speed regulation throughout the operating range. A separate tachogenerator channel provides tacho feedback to the analog controller, giving it a proportional velocity signal for closed-loop correction. The unit is classified as a motor for analog drives, so its feedback channels and electrical characteristics suit compatible MAC drive amplifiers. The controller can compare commanded motion with the returned signals and adjust motor current when speed or load changes occur. Power, encoder, and tacho connections use the established MAC interface arrangement, supporting installation with compatible cable sets and machine wiring layouts.
