Product Description:

The MAC025C-0-QS-4-E/040-B-0/WI652LV/S007 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for machine axes driven by analog command signals, it converts controlled electrical input into precise rotary motion for packaging, printing, and material-handling equipment. It serves as the electromechanical element in closed-loop positioning systems, working with analog servo amplifiers to deliver repeatable torque and speed. Because the feedback functions are integrated into the motor, the paired amplifier can monitor shaft behavior directly during speed changes and positioning moves. This layout suits installations that do not require digital fieldbus control.

Mechanical proportions begin with motor size C, which gives the unit a mid-frame profile suited to compact machine layouts. The axial length code 025 indicates a short housing depth, helping the motor fit shallow frames without added spacers. Thermal management relies on natural convection, so heat leaves through the housing without external fans or liquid cooling. For electrical hookup, the three-phase leads terminate at a connector on side B, which can simplify cable routing when the rear of the motor faces the gearbox. The motor is supplied without a blocking brake, so holding force during power-off conditions must come from the drive or another external device.

Position supervision and commutation are handled by tachofeedback with an incremental or absolute encoder, allowing the motor to support legacy velocity loops as well as position-based control. The feedback arrangement includes an incremental encoder with standard mounting, which provides a consistent pulse train for compatible Rexroth drive cards. As a motor for analog drives, the unit accepts current or voltage reference signals instead of fieldbus messages. This format works well in control cabinets that still use analog setpoints and separate amplifier channels. It also helps maintain straightforward integration in machinery built around established analog motion architecture.
