Product Description:

The MAC041B-0-QS-3-E/050-B-0/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It is intended for position and speed control in automated machinery that requires precise, repeatable motion. The motor converts electrical commands from a compatible drive into controlled mechanical rotation. Its compact design supports applications such as pick-and-place axes, light conveying stations, indexing mechanisms, and other precision systems with limited installation space.

The motor has a frame size of 041, which establishes the primary housing, flange, and shaft dimensions. Its motor length B provides a compact axial profile while accommodating the QS winding arrangement used by the connected drive. Heat is removed through natural convection, so the installation does not require an external fan or liquid cooling circuit. Adequate clearance around the housing allows heat to pass into the surrounding air during operation. Power conductors terminate through a connector on side B, keeping the cable exit at the designated side of the housing and simplifying routing in linear machine layouts. Rotor speed is monitored through integrated tacho feedback, which supplies the analog drive with the signal needed for closed-loop speed regulation.

The motor includes a second shaft end, allowing an additional encoder or compatible mechanical device to be attached without changing the primary output connection. It is supplied with no blocking brake, so an external clamping device or drive-generated holding torque must secure a stationary load when required. This consideration is especially important for vertical axes that could move after motor power is removed. The unit is classified as a motor for analog drives and is compatible with controller platforms that use analog speed or torque references. Its integrated feedback supports responsive correction when operating conditions or connected loads change. The side-mounted power connection, compact housing, and passive cooling arrangement reduce the number of auxiliary components needed around the motor while preserving access to its electrical and mechanical interfaces.
