Product Description:
The MST130G-0035-NS-N0CN-D303 is a synchronous torque motor from Rexroth, part of their IndraDyn T series of synchronous motors, with a frame length of 130G. This torque motor comes with a winding code of 0035, featuring a winding resistance of 17.4 ohms and a winding inductance of 98.6 mH, which helps suppress high-frequency spikes in the motor supply, ensuring a smooth input supply to the servo motor. The discharge capacity of the winding of this motor is 15.7 nF.
The main specifications of this torque motor include a high-speed rating of 700 rpm while producing a torque of 80 Nm at this speed. The nominal speed for this motor is 350 rpm while generating a torque of 31.5 Nm. This motor is designed for rotary tables or machines, particularly for lathe machines, CNC, and drilling tables. The torque constant of this motor is significant, as it has a torque constant ratio of 6.4 Nm for every ampere of current consumed. Speaking of current ratings, this motor draws around 4.9 amperes of current at rated conditions, while the maximum current draw for this motor is approximately 18 amperes.
This motor features a low inertia design of 0.0038 kgm² despite having a medium speed of rotation. The mass of the stator of this motor is 10.2 kg, while the mass of the rotor is around 3 kg, making this motor lightweight compared to other motors designed by Rexroth. The insulation class according to the German EN 60034-1 standard is Class F, ensuring this torque motor can withstand a maximum temperature of 170 degrees Celsius without burning out the coil of the motor.
