Product Description:

The MAC090B-0-PD-4-C/110-A-0/WI520LV is an AC servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. It belongs to the product group intended for analog drives and delivers closed-loop torque and speed control to actuators, pick-and-place heads, and general motion axes on automated production equipment. Integrated feedback allows the motor to serve both speed-regulated and positioning tasks where repeatable motion is required. In automated machinery, it converts drive commands into smooth rotary motion for indexing, transfer, and feed movements.

Its mechanical interface starts with a centering diameter of 110 mm, allowing repeatable seating in gearbox or machine housings. This centering fit helps align the motor with the driven equipment and can reduce coupling stress during operation. Heat generated in the stator is released through natural convection, so no external blower or liquid circuit is required when the motor operates at the nominal speed of 1500 rpm. Electrical behavior is matched to drive amplifiers by winding code PD, which identifies the resistance, inductance, and current values used for this frame size. Power is supplied through a connector on side A, which can simplify cable routing when the motor is installed with the shaft facing the work zone.

For speed feedback, the motor includes a tachogenerator and can also accept an incremental or absolute encoder; the standard position device is an incremental encoder mounted in the standard flange. The tachogenerator produces 3 V/1000 rpm, providing a proportional analog signal that many analog controllers use for speed regulation, and it has a standard tacho quality rating suitable for general-purpose axes. Because the model is supplied without a blocking brake, any holding function must be provided by drive torque or an external mechanical lock when the machine is powered down. This feedback arrangement supports applications that use analog speed control together with encoder-based position monitoring.

Internal Product Review

  • ‘‘The MAC090B-0-PD-4-C/110-A-0/WI520LV is a highly capable AC servo motor for analog drives with natural convection cooling and a 1500 min-1 nominal speed. Tachofeedback with incremental or absolute encoder support, paired with standard incremental position feedback mounting, gives the motor practical integration flexibility for legacy motion systems. A side-A power connector further streamlines installation, making the MAC motor a very solid choice for stable analog servo applications.’’
