Product Description:

The MAC041B-0-BS-4-E/050-A-0/WI673LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, it converts electrical commands from compatible controllers into precise shaft rotation for positioning or speed regulation in automated equipment. Its compact housing is suitable for multi-axis gantries and other machines where installation depth is limited. Support for standard Indramat cabling also allows the motor to connect to compatible power and feedback equipment without requiring a specialized wiring arrangement.

The motor uses natural convection to remove heat, so no external blower or liquid-cooling circuit is required. Its mechanical envelope combines a B frame length with a motor size of 041, keeping the housing compact and the rotor inertia low for light-duty axes. Electrical power reaches the stator through a connector on side A, allowing cables to be routed alongside adjacent motors in closely spaced installations. Rotor position is measured by an incremental encoder installed in the standard mounting recess. This feedback arrangement supplies quadrature pulses and an index signal to the analog drive for velocity monitoring, position tracking, and homing functions. Passive cooling also avoids fan noise and removes the need to provide space for auxiliary cooling equipment around the motor housing.

The motor is supplied without a blocking brake, so holding torque must be provided by the drive or a mechanical lock when power is removed. Applications that require a different feedback arrangement can use tacho feedback with an incremental or absolute encoder, providing options for position and speed monitoring. The motor is compatible with analog drive controls, including systems that use ±10 V command interfaces in established automation equipment. Its feedback options support use in pick-and-place tables, laboratory devices, indexing mechanisms, and other light automation stations that require controlled rotary motion. The side-mounted power connection helps reduce cable interference, while the compact frame supports installation in machinery with limited axial clearance.
