Product Description

When examining motors for a certain application, knowing about the motor’s nameplate ratings is imperative. Depending on the manufacturer, the nameplate’s design or content may slightly vary. Generally speaking, however, the nameplate provides details about the machine’s type, identification, serial number, safety categories, and other rated parameters. Upon looking at Rexroth’s MAF130B-0100-FQ-M0-AH0-05-N1's nameplate, the rated speed, torque, current, and power are the basic parameters that you can immediately see. Besides the rated parameters, the type identification also provides a way to determine other qualities of a particular motor at a glance. 

In this case, assuming you’re familiar with Rexroth’s type code for its MAD/MAF motors, you can immediately determine that the MAF130B-0100-FQ-M0-AH0-05-N1 belongs to the MAF130B family, has a 0100 winding type, FQ cooling, and M0 encoder, among others. Based on its nameplate ratings, the MAF130B-0100-FQ-M0-AH0-05-N1 has the following rated parameters: 1000 rpm, 112 Nm, 28.4 A, and 11.7 kW. Since motors use electricity as the input to provide mechanical power, the torque constant for motors is another useful parameter for evaluating motor efficiency indirectly. For this motor model, the torque constant is 4.25 Nm/A, which implies that increasing the input current by one ampere increases the torque output by 4.25 Nm. Without a blocking brake, the MAF130B’s rotor moment of inertia is 0.079 kg (m^2). 

The MAF130B-0100-FQ-M0-AH0-05-N1 operates normally between the ambient temperature range of 0 and 40 degrees Celsius. Its motor housing and components have an overall thermal class of 155. As mentioned earlier, the MAF130B-0100-FQ-M0-AH0-05-N1 employs FQ, or liquid cooling, that dissipates 1.9 kW during operation. The inlet temperature of the cooling system operates between 10 and 40 degrees Celsius. Due to its liquid cooling system, the motor reaches 63% of steady-state temperature in as little as 3.5 minutes.
