Product Description

The MAC092B-0-QD-4-C/095-B-1/DI520LV belongs to Rexroths flagship motor series, the MAC AC motor series. It has a centering diameter of 95 mm, measured on the shaft side. Specifically derived from the MAC092 family, the MAC092B-0-QD-4-C/095-B-1/DI520LV features impressive characteristics, making it suitable for high-accuracy applications. Its Tacho voltage feedback with an incremental encoder allows monitoring of the motor speed and position during operation. The Tacho voltage feedback assigns a proportional value of the potential difference to the motor speed. For most of Rexroth Bosch’s electric motors, the Tacho voltage feedback is a common feedback mechanism. The incremental encoder of this motor model employs shock-damped mounting. 

Aside from its feedback and encoder, the MAC092B-0-QD-4-C/095-B-1/DI520LV incorporates a standard blocking brake that fixes the rotor position during a de-energized state. During nominal operation, the MAC092B-0-QD-4-C/095-B-1/DI520LV reaches a base speed of 2000 revolutions per minute. The rated speed of the motor pertains to the speed attained by the motor during a no-load condition. For synchronous motors, the rated speed is equal to the synchronous speed. On the other hand, for asynchronous motor types, the rated speed is slightly lower than its synchronous speed. Another operating condition that is important for motor operation is the stall or locked-rotor condition. During this mode of operation, the rotor is stationary, but the motor draws power from the supply. At this condition, the MAC092B-0-QD-4-C/095-B-1/DI520LV reaches a torque and current of 7.2 Nm and 11.9 A, respectively. 

Depending on the motor and controller combination, the maximum torque achievable by the MAC092B-0-QD-4-C/095-B-1/DI520LV varies. Assuming uniform voltage for all cases, the maximum current attainable by this motor model is 17.4 A. The MAC092B-0-QD-4-C/095-B-1/DI520LV depends on <<natural convection>> to lower motor temperature during or after operation.
