Product Description:

The Bosch Rexroth Indramat MAC025B-0-ZS-2-E/040-A-0 is a permanent-magnet AC servo motor designed for controlled motion in industrial automation equipment. It operates with compatible analog drive amplifiers to provide position or speed control for packaging machinery, pick-and-place systems, indexing equipment, and other lightweight axes. The motor converts regulated electrical current from the drive into rotary mechanical output at the shaft. Its compact housing allows installation where available space is limited, including machine layouts that use small gearheads, belt stages, or direct couplings. Closed-loop operation allows the connected drive to correct motion as the load or commanded speed changes.

Heat generated by the stator windings is removed through natural convection, eliminating the need for an external fan or liquid-cooling circuit. The installation must provide adequate clearance around the housing so that air can circulate and carry heat away from the motor surface. The model has a motor size of 025 and a motor length of B, providing a compact mechanical envelope for smaller motion systems. Phase conductors leave the housing through a connector on side A, which supports organized cable routing when the shaft faces the machine centerline. Rotor speed and position information are transmitted to the drive through integrated tacho feedback. The resulting analog signal enables the amplifier to regulate motor current in response to actual shaft motion without relying on a digital encoder.

The motor is supplied without a blocking brake, so an external clamp or continuous drive excitation is required when a stationary load must be held. It is classified as a motor for analog drives and is compatible with legacy MAC control systems that supply sinusoidal motor current and process tachometer signals. The unit belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. Its permanent-magnet rotor supports responsive acceleration and controlled deceleration on axes with low or moderate inertia. The housing and mounting arrangement support rigid attachment to a machine frame, while the compact shaft interface accommodates couplings used in automated positioning systems. Cable routing, cooling clearance, and external load-holding provisions should be considered when integrating the motor into an operating machine.
