First, the disassembly of the motor
Before disassembling the motor, first unplug the motor and the controller. At this time, record the one-to-one correspondence between the color of the motor lead and the color of the controller lead. Clean the operating area before opening the motor cover to prevent debris from being attracted to the magnetic steel inside the motor. Make a mark on the relative position of the end cap and the hub. Note: Be sure to loosen the screws in a diagonal order to avoid deformation of the motor casing. The radial clearance between the rotor and the stator of the motor is called the air gap (air gap), and the air gap of the motor is generally between 0.25 and 0.8 mm. After disassembling the motor to eliminate the motor failure, it must be assembled according to the original end cap mark, which can prevent the broom phenomenon after the secondary assembly.
Second, the lubrication of the internal gear of the motor
If the noise of the gear hub motor and the brushless gear hub motor starts to increase, or the gear in the motor is replaced, all the tooth surfaces of the gear should be coated with grease, generally using No. 3 grease or manufacturer-specified lubricating oil.
Third, the assembly of the motor
Before assembling the brush motor, please check the elasticity of the spring inside the brush holder, check whether the carbon brush and the brush holder are rubbed, check whether the carbon brush can reach the maximum stroke in the brush holder, and pay attention to the correct positioning of the carbon brush and the phase changer. In order to avoid bad carbon brushes or brush grips.
When installing the motor, first clean the impurities on the surface of the motor components, so as not to affect the normal operation of the motor, and the hub body must be fixed and strong, so as to avoid the components being impacted and damaged due to the strong attraction of the magnetic steel during installation. The detection of 36V is normal, the controller output is 5V, 12V is normal, and the motor resistance is normal. Connect the motor directly to the 36V battery and the motor is running normally.
