Product Description:

The MAC090C-0-GD-4-C/130-B-1/WI581BX/S003 is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It drives individual machine axes in industrial automation where precise torque and speed control are needed for coordinated motion. By converting electrical power into controlled rotary movement, the unit positions tooling, conveyor sections, or packaging mechanisms. Its sealed construction allows operation without separate cooling hardware, making it suitable for dense machine layouts or retrofit situations that lack forced ventilation.

A centering shoulder measuring 130 mm simplifies alignment with mating gearboxes or machine frames and helps keep radial runout low. Thermal energy is dissipated through natural convection, so no fan wiring or added cooling equipment is required. Three-phase conductors terminate through a connector on side B, which directs the cable away from moving parts and improves access around the housing. The GD winding code sets the motor’s rated voltage constant and current limits. Rotor position and speed are reported by an incremental encoder with standard mounting, supplying uniform pulse trains to the drive for closed-loop regulation during indexing and speed-controlled motion.

A standard blocking brake is integrated to hold the shaft when power is removed, preventing unintended motion on gravity-loaded axes. The internal wiring supports tacho feedback, incremental encoder, or absolute encoder signals, allowing the motor to work with compatible feedback arrangements without external adapters. The motor is a motor for analog drives, confirming compatibility with Indramat MAC series amplifiers that use ±10 V command loops. Consistent velocity data is ensured by standard tacho quality, which keeps signal ripple low so speed corrections remain stable during continuous or cyclic operation. This arrangement supports steady response during repeated starts, stops, and speed changes in automated equipment.
