Product Description:

The MAC025A-0-WS-2-E/040-A-0/S001 is a servo motor manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Designed for positioning and speed-control duties, it interfaces with analog servo amplifiers to drive light-to-medium loads in packaging machines, handling modules, and printing lines. The unit converts electrical input into controlled mechanical rotation, allowing automation systems to synchronize axes, follow electronic cams, and maintain constant tension. Its compact design is suited to machinery that requires accurate, repeatable movement without the size and weight of a larger motor.

The motor dissipates heat through natural convection, so the mounting space must permit unobstructed airflow to keep the winding temperature within acceptable limits during continuous operation. Rotor speed is reported through a built-in tachometer feedback generator, enabling the drive to close the velocity loop without an external encoder. The motor size of 025 provides a compact magnetic structure for applications with moderate continuous torque requirements. Its A frame length keeps the housing short and supports installation in machinery with limited axial space. Power is delivered through a connector on side A, allowing the cable to be routed toward equipment located on that side of the housing. The unit has no blocking brake, so stationary loads must be held by drive-applied torque or an external mechanical lock when required.

The unit is configured as a motor for analog drives, allowing a compatible amplifier to regulate motor current in response to analog control commands. This arrangement supports established motion-control systems that do not rely on digital fieldbus communication between the amplifier and motor. The WS winding code identifies the winding arrangement used for the motor’s electrical characteristics, including its resistance, inductance, voltage, and current requirements. Matching those characteristics with a compatible servo amplifier helps maintain stable current regulation and predictable torque production throughout the operating range. The integrated feedback signal allows the amplifier to detect speed changes caused by varying loads and correct the commanded output during positioning, tension-control, or constant-speed operation.
