Product Description

The MAF130B-0200-FR-S0-BH0-05-N1 is one of Rexroth’s largest MAF motors and boasts high driving capabilities and unique features. MAF motors are specifically well-regarded because of their unique liquid cooling system. This liquid cooling system may come with either a connection thread or an enclosed rapid cooling action coupling. The difference between the two is that the quick coupling provides protection against leakage. Furthermore, the latter can also be released at maximum pressure. Throughout operation, the motor’s coolant temperature stays between 10 and 40 degrees Celsius. The motor itself can operate at an ambient temperature above 0 degrees Celsius but below 40 degrees Celsius.

Considering the MAF130B-0200-FR-S0-BH0-05-N1s cooling system’s characteristics, the thermal time constant for this motor model is 3.5 minutes. Among all Rexroth’s products and motor series, the MAF motor series features the lowest thermal time constant, which leads to faster cooling times. During continuous operation, the surface temperature of this motor may reach somewhere above 60 degrees Celsius. At disconnection, the motor reaches thermal equilibrium with the environment in less than 18 minutes. At a rated or normal speed of 2000 rpm, the MAF130B-0200-FR-S0-BH0-05-N1 provides an ideal torque output of 100 Nm. 

By adjusting the drive voltage or frequency, the motor’s operating point can be shifted. In particular, the motor may safely operate at a maximum speed of 7500 rpm. This maximum speed is limited by the motor’s standard bearing. Meanwhile, when certain conditions are met, the MAF130B-0200-FR-S0-BH0-05-N1 can provide a maximum torque output of 220 Nm. To operate this motor at a specific operating point, further consultation with Rexroth’s official datasheet for MAF130 motors is a must. Considering that the MAF130B-0200-FR-S0-BH0-05-N1 weighs 82 kilograms, Rexroth’s MAF motor manual also provides special hoisting and installation instructions.
