Product Description:

The MAC090C-0-KD-4-C/110-A-0/WI522LV/S001 is an AC servo motor designed and manufactured by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. Engineered for analog drive controllers, the model delivers commanded torque and speed for positioning tables, packaging equipment, and general automation axes. By combining an internal tacho generator with optional encoder feedback, the motor supplies real-time velocity and position signals so the associated drive can close its control loops and maintain accurate motion under varying mechanical loads.

The stator uses a KD winding configuration that sets resistance and inductive reactance for legacy Indramat amplifiers. Continuous operation is rated at 1500 rpm, giving suitable headroom for medium-speed machining or feed movements. Thermal energy leaves the housing through natural convection, so the installation must allow free air circulation around the ribbed frame. Power conductors terminate in a keyed connector on side A, reducing strain on flexible cable sets that follow moving carriages. The built-in tacho generator outputs 3 V/1000 rpm, enabling the drive to derive speed feedback directly from an analog voltage proportional to rotor velocity.

Axial alignment during mounting is aided by a 110 mm centering diameter that matches standard Indramat flange patterns. For higher-resolution feedback, the motor supports incremental or absolute encoder interfaces with tacho feedback, allowing the control system to switch between coarse speed regulation and fine positional indexing. The primary position device is an incremental encoder with standard mounting, ensuring compatibility with common reader heads and retaining ring hardware. The tacho generator is classified as Standard. The motor has no blocking brake, so holding torque must be provided by the drive or an external mechanical lock when the axis is at rest.
