Product Description

The MAF130B-0250-FQ-M2-BR1-35-V1 is Rexroth’s original product, derived from the well-known MAF motor series. The MAF motor series is one of Rexroth’s asynchronous housing motors that features a  liquid cooling mode. The MAF130B-0250-FQ-M2-BR1-35-V1 belongs to the MAF motor series, with a frame classification of 130B. MAF130B motors may come in different winding types that designate the motor’s rated speed. Motors with a winding type of 0250 indicate that the motor's rated speed is 2500 rpm. According to Rexroth’s MAF130B datasheet, the rated power of the MAF130B-0250-FQ-M2-BR1-35-V1 is 23.56 kW. At this rated power, the motor’s torque and current are 90 Nm and 58.8 A, respectively. 

Although the rated speed of the MAF130B-0250-FQ-M2-BR1-35-V1 is 2500 rpm, the motor experiences de-rating to some degree when the speed approaches 1500 rpm. This de-rating is mainly because the motor’s key speed is 1500 rpm. The motor’s cycle duration is 5 minutes, assuming a 44% duty cycle. The duty cycle of motors represents the motor's on-time as a percentage of the motor’s total operating time. During operation, the MAF130B-0250-FQ-M2-BR1-35-V1's holding brake may halt a maximum torque of 100 Nm. The blocking brake for this motor model is type 1, which works when electrically released. 

The MAF130B-0250-FQ-M2-BR1-35-V1 also features a standard bearing and M2 encoder. It also has a power connector on side B and a shaft type R. Motors with a shaft type of R feature labyrinth sealing and a complete balanced keyway. The labyrinth sealing is particularly useful for preventing leakage of the lubricating oil around the motor’s drive side. Based on Rexroth’s datasheet, the leakage capacitance for this motor model is 13.2 nF. Finally, because of its B35 construction, the MAF130B-0250-FQ-M2-BR1-35-V1 supports flange or foot mounting methods.
