Product Description:

Bosch Rexroth Indramat manufactures the MAC041C-0-LS-3-E/050-B-0 servo unit as part of the MAC AC Servo Motors series. This product is an AC servo motor intended for analog velocity and position control in automated machinery. It transforms controller current into controlled shaft rotation, allowing conveyors, small indexing tables, and handling modules to follow drive commands with tight accuracy. The motor’s overall design targets installations where limited space, moderate torque demand, and passive cooling are acceptable, offering a compact drive element for equipment that uses analog drive amplifiers and closed-loop speed control.

The electrical and mechanical form factors begin with the Motor Size C frame, which sets the outside diameter and flange dimensions used for mounting. A stack designation of Motor Length 041 keeps rotor inertia low so speed changes are fast during repeated motion cycles. The internal copper arrangement follows Winding Code LS, a selection that sets phase resistance and inductance suited to analog current loops. Thermal energy leaves the housing by natural convection, eliminating fans and reducing maintenance points in compact installations. The unit is delivered without a blocking brake, so any vertical axis that must remain at standstill needs retention from the drive or an external clamp.

Feedback and cabling features complete the profile. Integrated tacho feedback produces a proportional voltage that the drive uses for real-time speed regulation during changing load conditions. The optional second shaft end allows the connection of a resolver or mechanical tachometer without altering the primary load interface. Mains power reaches the stator windings through a connector on side B, which keeps the cable run on the non-drive end for easier routing inside tight enclosures. This model is classified as a motor for analog drives and is used with legacy MAC amplifiers that rely on continuous analog command signals.
