Product Description
Smaller motor frames are more suitable for high-speed applications. Typically, for most of Rexroth’s products, smaller motor frames have higher speed characteristics but lower torque and power throughput. For higher-torque applications, acquiring motors with a larger frame type is a smart choice but is generally more expensive. For most industrial and production applications, Rexroth’s MAD motor series has an excellent reputation and an impressive track record. Under this motor series, the MAD100B-0150-SA-M2-KQ0-05-N1, one of the smallest motor models, originated. Weighing only about 43 kilograms, this motor model is compact and appropriate for applications in which space is a major consideration.
Regardless of its small construction, Rexroth managed to equip the MAD100B-0150-SA-M2-KQ0-05-N1 with a powerful set of axial cooling fans that keep the motor’s temperature at desirable levels. Compared with other MAD motors, the MAD100B-0150-SA-M2-KQ0-05-N1 has a small thermal time constant of 20 minutes. Most MAD motors have a high thermal constant in the range of 30 minutes or higher. The thermal time constant for motors is an important quantity that provides an overview of the thermal characteristics and cooling properties of the motor. Lower thermal time constants imply faster cooling times and temperature stabilization. In terms of its torque capabilities, this motor model may transmit a torque value between 30 Nm and 68 Nm.
As mentioned earlier, smaller motor frames can drive loads at higher speeds. Particularly, the MAD100B-0150-SA-M2-KQ0-05-N1 operates at a wide speed range, starting from its base speed of 1500 rpm up to a maximum speed of 9000 rpm. The maximum speed may be further increased for motors equipped with a high-speed bearing. Rexroth’s datasheet for MAD100B motors provides other details, such as the leakage capacitance (5.7 nF) and rotor moment of inertia (0.019 kg x m^2).
