Rear hub motor with integrated torque sensor function, features and mounting connections
Nov 22, 2018

Since the high-precision detection instrument is particularly important for the reliability of the motor test data, it is directly related to the authenticity of the test result, so the rear hub motor is required to have an integrated torque sensor. These sensors measure torque and speed and measure torque by measuring shear stress instead of torque stress.


The rear hub motor with integrated torque sensor has a compact design and occupies a very small space. The high lateral protection allows the connecting shaft to be directly connected to the flange without the need for other support shafts and can withstand higher dynamic loads; its extremely high Torsional rigidity eliminates the resonance of the torque. Since the torque measuring flange works without bearings and slip rings, it is completely maintenance-free.


In addition, the rear hub motor with integrated torque sensor adopts a modular design structure with rated torques of 50 Nm, 100 N·m, 200 N·m, 500 N·m, 1 kN·m, 2 kN·m, 3 kN·m, 5 kN·m and 10 kN·m with an accuracy of 0.1%, a rated speed of 8 000-15 000 r/min, and a minimum speed of 2 r/min. The measured value is output through the voltage and frequency signals, and the amplifier with HBM can be directly connected to the computer, which makes subsequent data processing and analysis work more convenient.


The installation of the rear hub motor with integrated torque sensor is divided into two parts: mechanical connection and electrical connection. In order to avoid the additional bending moment generated by the deformation of the sensor, the motor, sensor and load to be tested must have good coaxiality during installation. There should be a certain distance between the two coupling halves.
