Product Description:
The MAC025A-0-WS-4-E/040-A-1/WI651LV is a servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Engineered as a motor for analog drives, it converts current commands from compatible amplifiers into precise mechanical motion for indexing tables, small gantry axes, and other position-critical automation applications. Its compact form supports installation in machinery where available axis space is limited. The frame and flange geometry follows established MAC dimensions, allowing compatible mounting hardware and couplings to maintain accurate mechanical alignment.
The WS winding code establishes the voltage constant and rated current needed for the drive to produce the required torque without magnetic saturation. Thermal management relies on natural convection cooling, which allows heat to leave the stator surface without fans or forced airflow. This passive cooling method reduces the number of moving components around the motor and simplifies airflow requirements inside the machine. Power reaches the stator windings through a connector on side A, keeping the power cable routing predictable in compact installations. The motor has a motor size of 025 and a motor length of A. These proportions provide a short overall body while accommodating the magnetic stack required for continuous operating cycles.
A standard blocking brake is integrated into the motor to hold the shaft when the drive is disabled, helping prevent load drift on vertical or overhung axes. For velocity supervision, the motor uses tacho feedback, which supplies an analog speed signal to the connected drive amplifier. This signal allows the amplifier to detect speed deviations and adjust motor current during changing load conditions. An incremental encoder with standard mounting provides digital position pulses for applications that require position tracking or controlled indexing. The encoder output enables the controller to monitor shaft movement while the tacho channel supports responsive speed regulation. Both feedback paths are available without adding a separate external measuring device to the driven axis.
