Measuring device for disc drive motors

Abstract

The invention discloses a measuring device of a disc type driving motor. The measuring device comprises a connection shaft installed in a framework, a torque and revolving speed sensor is arranged on the connection shaft, two ends of the connection shaft are connected with a first motor to be detected and a second motor to be detected through rotation shafts respectively, the first motor to be detected is connected with a driver, a battery pack is connected with the driver, a power supply end battery voltage measuring device is arranged between the driver and the battery pack, the second motor to be detected is connected with an adjustable resistive load, and a power generation end current and voltage measuring device is arranged between the second motor to be detected and the adjustable resistive load. By means of the structure, the measuring device is simple in structure, low in manufacturing cost, simple in testing method and capable of effectively measuring operation characteristics of the motor required to be driven by the driver under different working conditions and independently and comprehensively testing performance parameters of the motor, and the measuring device can be widely applied to motor industries and detection mechanisms for testing performances of the motor, particularly the performances of the motor required to be driven by the driver.

Description

technical field [0001] The invention relates to a measuring device for a motor, in particular to a measuring device for measuring a high-power disc drive motor. Background technique [0002] The traditional motor measurement method is to use the method of magnetic powder brake, hysteresis dynamometer, eddy current dynamometer or electric dynamometer to measure the load of the motor. Different measurement methods have their limitations. Not very applicable, hysteresis and eddy current dynamometers are not suitable for low speed, electric dynamometer equipment is more complicated, and the cost is relatively high. For disc drive motors, especially disc motors used in the field of electric drive, it is necessary to consider its characteristics at low speed and high speed when measuring, and the motor works under the control of the driver. When measuring the performance of the motor, it is necessary to remove the influence of the drive, so the traditional measurement methods are...

For disc drive motors, especially disc motors used in the field of electric drive, it is necessary to consider its characteristics at low speed and high speed when measuring, and the motor works under the control of the driver. When measuring the performance of the motor, it is necessary to remove the influence of the drive, so the traditional measurement methods are not suitable
