Product Description:

The Bosch Rexroth Indramat MAC090C-0-GD-4-C/110-A-1 belongs to the MAC AC Servo Motors series and serves as a torque generator for motion axes in industrial automation. Used with analog drive amplifiers, the motor converts command voltages into controlled rotary movement for pick-and-place systems, carton formers, and indexing tables. Its compact frame, matched rotor inertia, and low electrical time constants support repeatable speed profiles during continuous production shifts. This operating style suits machinery that depends on smooth acceleration and predictable settling behavior.

The housing is machined for a 110 mm centering diameter, so the flange aligns accurately with standard mounting faces and maintains concentricity during high-speed operation. Heat is removed through natural convection, so the motor can be installed without external blowers when surrounding air can circulate freely. Power enters through a connector on side A, which helps keep cable routing organized when the shaft faces the load. The motor uses a GD winding, which sets the coil resistance and back-EMF constant used by the drive to regulate current. For closed-loop control, the unit accepts tacho, incremental encoder, or absolute encoder feedback, so feedback resolution can be matched to the axis requirement.

Operational stability at standstill is provided by a standard blocking brake that clamps the shaft whenever the drive disables torque. Speed regulation quality is supported by the motor’s standard tacho quality, which suits velocity loops with medium servo bandwidth. As a motor for analog drives, the unit can be paired with classic transconductance amplifiers and used in systems that retain an analog control architecture. This makes the motor suitable for equipment that requires controlled rotary motion without a digital fieldbus-based drive platform. It can also be applied where existing amplifier response and tuning behavior must remain consistent.
