Product Description

The MAD and MAF motor series are closely related to one another. In fact, objectively speaking, the only difference between these two series is the cooling mechanism. The MAD motors employ traditional surface cooling via their mounted surface blower fans. On the other hand, the MAF motors incorporate a liquid cooling system that facilitates faster cooling. Both motor series are best for low- to medium-speed applications requiring high driving torque. Physically speaking, both the MAD and MAF motor series feature some of the largest and strongest motors by Rexroth. 

As an example, the MAF130B-0200-FQ-S2-RH0-35-V3 by Rexroth provides a rated torque of 100 Nm at a rated power of 20.9 kW. With such output, this motor model is capable of meeting the heaviest industrial demands. During normal operation, the expected current draw across the motor’s output side is 52.7 amperes. Normally, the shaft of this motor model revolves at a rate of 2000 times per minute. Like other motors, the MAF130B-0200-FQ-S2-RH0-35-V3 also functions well over a wide speed range. Owing to its reinforced bearings, the maximum speed of this motor is 7500 rpm. Because its key speed is 1500 rpm, however, the motor experiences de-rating before the nominal speed, particularly on its torque and power output. 

Aside from its nameplate ratings, another strong feature of the MAF130B-0200-FQ-S2-RH0-35-V3 is its single-turn encoder that uses 2048 increments. Because of the encoder, this motor model accurately monitors key parameters during operation. Such monitoring is heavily utilized in high-accuracy and servo applications. When operated at peak conditions, the MAF130B-0200-FQ-S2-RH0-35-V3 may supply a maximum torque of 220 Nm and a maximum power of 42.86 kW. Assuming the same peak power while keeping the terminal voltage constant, the MAF130B-0200-FQ-S2-RH0-35-V3's peak current is 108.9 amperes.
