Product Description:

The MAC090C-0-ED-4-C/110-B-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat and supplied within the MAC AC Servo Motors series. It is intended for closed-loop motion tasks where an analog drive amplifier commands speed or torque, allowing machinery such as packaging stations or material-handling axes to receive precise rotary power. Because it operates with an external analog amplifier, the motor can support smooth speed regulation and controlled torque response during changing load conditions. Its integrated feedback arrangement allows the motor and drive to function as a compact motion package for positioning axes and speed-regulated machinery.

Mechanical interface accuracy is supported by a centering pilot of 110 mm, which aligns the motor housing with mounting flanges and gearboxes. This pilot also helps reduce alignment error between the motor and attached drive components. Heat is dissipated through natural convection, so no fan or liquid circuit is required. Incoming power is routed through a connector on side B, placing the power leads opposite the shaft for straightforward cable management in tight cabinets. Electrical behavior is tied to winding designation ED, a code associated with the resistance, inductance, and voltage constant expected by the paired analog drive. The motor has no blocking brake, so holding force during power-off must be supplied by external clamping or drive torque when the axis must remain stationary.

Speed and position signals are supported by tacho feedback with an incremental or absolute encoder, so the motor can provide velocity and position information for the connected control loop. The motor is categorized as a motor for analog drives, emphasizing compatibility with amplifiers that process ±10 V reference signals rather than fieldbus commands. Rotor speed monitoring uses a tachogenerator built to standard accuracy, which is suitable for general-purpose regulation without high-precision calibration. Shaft position is read through an incremental encoder with standard mounting, which keeps the feedback arrangement consistent with common MAC family hardware. This combination of feedback elements supports both speed regulation and position supervision in the external control system.
