Product Description
Liquid-cooled motors provide unmatched cooling capabilities. Compared to air-cooled motors, liquid-cooled motors provide a more stable temperature profile and immunity against mechanical noise. During operation, air-cooled motors tend to have high mechanical noise due to the air current passing through the internal components of the motor. When it comes to manufacturing the best liquid-cooled motors, Rexroth Bosch Indramat dominates the market with the MAF motor series. Rexroth designed the MAF motor series to meet continuous high-torque loads. Depending on the motor frame type and size, the motor ratings vary. For comparison, MAF130 motors generally have higher ratings compared to MAF100 motors. Under MAF130 motors, MAF130C motors have higher ratings compared to MAF130B motors.
The MAF130B-0250-FQ-M2-HH0-05-N1 is a product variation derived from the MAF motor series featuring a size B 130-frame. At no-load operation, the MAF130B-0250-FQ-M2-HH0-05-N1's speed is 2500 rpm. By reducing the motor’s torque, the motor's effective speed increases. For this motor model, the effective maximum speed is 7500 rpm. At maximum speed, the motor’s current may reach its peak value of 126.6 A. Keeping the voltage constant, the maximum power of this motor model at the peak current is 48.3 kW. For applications requiring extra high torque, the MAF130B-0250-FQ-M2-HH0-05-N1 can supply a maximum torque of 210 Nm.
To accommodate the MAF130B-0250-FQ-M2-HH0-05-N1's maximum current, Rexroth’s documentation recommends a minimum power wire cross-section of 16 square millimeters. At any point during operation, the cooling system’s inlet temperature fluctuates only between 10 and 40 degrees Celsius. The maximum power that the cooling system may dissipate is 2.23 kW. Even with its cooling system, the MAF130B-0250-FQ-M2-HH0-05-N1 supports all flange attachment variations, as elaborated in Rexroth’s manual. Finally, the MAF130B-0250-FQ-M2-HH0-05-N1 incorporates an encoder of type M2, which employs 2048 increments during operation.
