Product Description

The mechanical bearing directly influences the speed rating and capabilities of an AC motor. These bearings minimize friction during rotation and ensure efficient torque and power transfer from the motor to the load. Rexroth’s MAD100 motors may come with any of the following bearing types: A, H, and N. A-type bearings imply a fixed bearing type on side A, while H-type bearings refer to high-speed bearings. Finally, N-type bearings are the standard for most of Rexroth’s MAD motors. The MAD100B-0200-SA-S2-BH0-05-H1 is one of Rexroth’s MAD100 motors with a high-speed bearing. 

Without loads connected, the MAD100B-0200-SA-S2-BH0-05-H1 achieves a base speed of 2000 rpm. When optimized to run at maximum speed settings, this motor model can reach a speed of 11000 rpm, thanks to its H-type bearing. At a speed of 1500 rpm, however, the motor may deliver lower torque and power because of de-rating. This de-rating is the result of the motor’s key speed being 1500 rpm. For further details about the MAD100B-0200-SA-S2-BH0-05-H1's speed characteristics, please visit MAD100B’s technical data under Rexroth’s MAD/MAF manual. Other features of this motor model include SA cooling, an S2 encoder, and an H-type shaft. 

Based on the nameplate of the MAD100B-0200-SA-S2-BH0-05-H1, the rated parameters are as follows: 14.6 A, 28 Nm, and 5.9 kW. Assuming that at the rated power, the rated line current flows through the motor, then the terminal voltage of the motor during the rated condition is around 404 V. When operated in the locked-rotor condition, the motor’s parameters are as follows: 15.3 A and 30 Nm. These measured parameters are the basis for the prudent design of the motor’s protection devices and ratings. Finally, based on Rexroth Bosch’s datasheet, the MAD100B-0200-SA-S2-BH0-05-H1 has the following maximum parameters: 28.9 A and 66.2 Nm.
