Product Description

Motors and generators work via the principle of electromagnetic induction. To put it simply, when a conductor experiences a changing magnetic field, a corresponding voltage is induced. Conversely, a voltage may also be induced when the conductor moves across a stationary magnetic field. This phenomenon paved the way for the invention of both motors and generators. The difference between the two is that motors require electrical input to provide mechanical output, while generators require mechanical input to provide electrical output. One of the most sought-after brands that manufactures high-quality AC motors is Rexroth Bosch Indramat. 

Out of the several motor series offered by Rexroth, the MAC AC motor series is a popular choice for driving high-speed, medium-torque industrial loads. The MAC093A-0-WS-4-C/130-B-0/WA612XX/S005 is a specific product model under the MAC093 family line. This motor model has a frame size of A, equating to a total length of 0.275 meters, and a 130-mm centering diameter. The power connector for this motor is on side B, the side parallel to the shaft side. It has a rated speed of 2000 rev/min, but it may also operate at other speeds. For low-speed applications, the output torque of the motor may approximate its maximum torque value of 26.2 Nm. During the standstill test, the torque falls to around 9.2 Nm. 

The torque-speed characteristics of the MAC093A-0-WS-4-C/130-B-0/WA612XX/S005 are in Rexroth’s documentation for MAC motors. At the rated speed, the torque value is approximately 6 Nm. Depending on the DC bus voltage, the breaking point of the motor may vary. The breaking point is the point in the torque-speed curve of the motor that signifies the point at which the motor torque starts to fall from maximum. For type 1 bus voltage, the breaking point is around 2200 rpm. For type 2 bus voltage, the breaking point is approximately equal to the rated speed, while at type 3 bus voltage, the breaking point is 1700 rpm.
