Product Description:
The MAC041C-0-LS-3-E/050-B-1 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. This compact rotor-stator unit is intended to interface with analog servo amplifiers used in legacy and retrofit platforms. By delivering controlled electromagnetic torque, the motor lets machine builders synchronize conveyor sections, regulate indexing tables, and execute moderate-inertia moves with consistent accuracy. It is well suited to axes that require repeatable low-to-medium power motion without the complexity of digital network control.
Its factory-installed blocking brake provides static holding torque when power is removed, helping prevent vertical or offset loads from drifting. Thermal management relies on natural convection, eliminating auxiliary fans and allowing the housing to dissipate heat without forced airflow. Position and velocity data are supplied through tacho feedback, while a dedicated second shaft end provides a mechanical interface for an external encoder or coupling device when additional feedback hardware is needed. Power conductors enter through a connector on side B, which simplifies cable routing in crowded enclosures by keeping the opposite face clear for mounting. The stator uses the LS winding, a code associated with electrical values matched to analog drive cards. This arrangement supports straightforward integration with amplifier systems that monitor motor speed directly.
Mechanical proportions follow the size C frame, giving a square flange that mates with standard MAC gearbox adapters. The magnetic stack uses the 041 length, which increases active iron depth and raises continuous torque compared with shorter variants without changing the frame cross-section. Because the motor is supplied as a motor for analog drives, command signals are expected as ±10 V or current references rather than serial fieldbus data. This allows the unit to fit existing amplifier racks used in legacy motion systems that do not rely on digital communication modules.
