Product Description

When it comes to high-performing squirrel-cage motors, nothing beats the MAD/MAF motor series by Rexroth. The MAF motor series by Rexroth is much like the MAD motor series, with the exception of its cooling mechanism. The MAD motors feature a reliable set of axial blower fans that facilitate surface cooling, while the MAF motors use an external liquid cooling system. The MAD180C-0100-SA-S2-HG0-35-N3 originated from the MAD motor series, featuring a 180-frame type of size C. According to Rexroth’s documentation for MAD180C motors, the winding type dictates the speed at which the motor runs during no-load or nominal conditions. For this motor model, the rated speed is 1000 rpm. 

An interesting parameter included in Rexroth’s documentation is the key speed. The motor’s key speed is the speed at which the motor’s torque and power de-rate before achieving the rated speed. This de-rating behavior is present for some motor versions and is described by the motor’s characteristic curve. The MAD180C-0100-SA-S2-HG0-35-N3 has a key speed of 500 rpm, which is half its rated speed. During normal working conditions, the output torque of this motor model is 300 Nm. At this torque output, the corresponding current draw is 69 A at a rated power of 31.4 kW. 

When allowed to reach its maximum or optimum values separately, the MAD180C-0100-SA-S2-HG0-35-N3 achieves very high peak values. For instance, the maximum output torque of this motor model reaches 726.4 Nm. This much torque comes at the cost of reduced operating speed. During the peak operating period, the maximum power and current values for this motor model are 64.37 kW and 147.6 A, respectively. Finally, the MAD180C-0100-SA-S2-HG0-35-N3 has a standard bearing and a vibration severity grade of 3.
