Product Description:

The MAC041B-0-BS-2-E/050-A-0 is a servo motor built by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Intended for analog drive systems, the motor converts electrical commands into controlled rotational motion so machine axes can follow continuous setpoints. It supports velocity and torque regulation in packaging lines, printing machines, and small assembly fixtures. The motor can synchronize moving components with mechanical cams, line shafts, and other coordinated machine elements. Its compact design suits applications that require responsive motion within a limited installation area.

The motor is supplied with no blocking brake, so an external clamping device or drive-generated torque must hold the shaft stationary when required. Heat is removed through natural convection, eliminating the need for a fan or liquid-cooling circuit. This passive cooling method reduces the number of auxiliary components around the motor and allows straightforward installation in appropriately ventilated machinery. The motor uses tachogenerator feedback to send velocity information to the connected drive, allowing the controller to regulate current as operating speed changes. Its mechanical envelope has a frame size of 041 and a frame length of B, providing compact proportions for light- and medium-duty axes. These dimensions help the motor fit into small motion assemblies without requiring a large mounting area.

Electrical installation uses a connector on side A, providing a fixed cable exit orientation for consistent routing through the machine. The connector placement can reduce sharp cable bends when the motor is installed with the corresponding side facing the wiring path. Secure cable support should be provided near the housing to limit strain caused by machine vibration or repeated axis movement. The motor works with a compatible voltage-controlled amplifier that supplies the current needed for continuous speed and torque regulation. Its analog control arrangement is suitable for machinery that uses continuously varying command signals rather than digitally interpolated motion commands. Proper drive matching is necessary to ensure that the winding, feedback signal, and operating limits are compatible with the connected control system.
