Product Description:

The MAC093C-0-DS-4-C/110-B-0/WI634LX is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, this unit converts commanded current into mechanical rotation for closed-loop axis control in automated machines. By embedding speed and position feedback within the frame, the device integrates directly with legacy analog amplifiers used in packaging, printing, and material-handling equipment. This integrated design reduces the need for separate external feedback hardware and helps keep the motor assembly compact. It also suits retrofit installations where existing control cabinets already use analog command and feedback processing.

Its mounting interface features a centering diameter of 110 mm, matching standard mechanical flanges for accurate alignment. The frame corresponds to size 093, a profile that balances torque density with manageable inertia for mid-range axes. Under rated excitation, the rotor reaches a nominal speed of 4000 rpm, making the motor suitable for fast index cycles and responsive speed changes. This speed range supports applications that require short cycle times without relying on oversized transmission ratios. Heat generated during operation is removed through natural convection, eliminating the need for external blowers and simplifying cabinet layout. Power is supplied through a connector on side B, which helps keep cable routing clear of moving machine elements.

Drive matching is handled by winding code DS, whose electrical characteristics suit analog amplifiers that supply a constant current loop. For velocity supervision, the motor incorporates a tachogenerator that delivers 1.5 V/1000 rpm, and this analog signal is used by the controller for real-time speed regulation. Position information is produced by a standard-mounted incremental encoder, allowing the same shaft to support both speed and position loops. Using both feedback devices lets the drive separate continuous speed monitoring from position tracking within the same motor package. The motor has no blocking brake, so holding force must be provided by the drive or by an external mechanical lock when the axis is stopped.
