Product Description

If you are looking for a strong asynchronous AC motor that has a high power-to-weight ratio, look no further than the MAD/MAF motor series. The choice between the MAD and MAF motor series depends on the type of cooling you prefer. Comparing these motor series, the MAD motors use external fans for surface cooling, while the MAF motors use liquid cooling. For extreme environments such as industrial and production plants, liquid-cooled asynchronous motors offer greater advantages than air-cooled motors because of their efficient heat dissipation and immunity against dust and other foreign particulates. Another excellent benefit of liquid-cooled motors is that the heat extracted from the motor may be reused. 

A specific machine that originated from the MAF motor series is the MAF130C-0200-FQ-S2-BG0-05-N1. The MAF130C-0200-FQ-S2-BG0-05-N1 incorporates an output shaft with a sealing ring that extends the motor protection category to IP 65. Motors with this protection class have maximum protection against particulates and liquids during operation. With a nameplate power rating of 28.3 kW and a mass of 106 kilograms, this motor model provides high power capabilities for its weight. At this operating point, the motor transmits a shaft torque of 135 Nm. Based on Rexroth Bosch’s MAF motor documentation, the MAF130C-0200-FQ-S2-BG0-05-N1 has a rotor moment of inertia of 0.101 kg (m^2). 

Equipped with a standard mechanical bearing, the MAF130C-0200-FQ-S2-BG0-05-N1 operates well at a maximum speed of 7500 revolutions per minute. In no-load mode of operation, the machine delivers a nameplate speed of 2000 revolutions per minute. With a construction class of B05, this motor model allows various mounting orientations. To mount this motor model, screws must be placed on its flange. Detailed mounting instructions are in Rexroth’s official documentation for the MAF motor series.
