specific Embodiment approach 1
[0021] Specific implementation mode 1. Combination figure 1 with figure 2 Describe this embodiment, a device for improving the speed measurement accuracy of a flywheel motor, including a flywheel motor 1, a gear sensor 2 with a magnetic field sensing surface facing the flywheel motor rotor 1-2, a signal processing circuit board 3, a power signal line 4, and a signal processing circuit board Install the bracket 5 and the magnetic steel 6.
[0022] The flywheel motor 1 includes a flywheel motor stator 1-1 and a flywheel motor rotor 1-2, and tooth crests 1-3 and tooth valleys 1-4 are evenly distributed on the outer periphery of the flywheel motor rotor shaft. The flywheel motor rotor is a ferromagnetic material. The gear teeth of the gear are evenly distributed along the circumferential direction, and the sideline of the gear teeth is in the radial direction, and is parallel to the line connecting the middle point of the tooth tip and the geometric center of the gear. The out...
specific Embodiment approach 2
[0030] Specific Embodiment 2. This embodiment is a method for using a device for improving the speed measurement accuracy of a flywheel motor described in Specific Embodiment 1. The method is implemented by the following steps:
[0031] Step 1. Check the line connection, power on the flywheel motor controller, and power on the speed measuring device through the power signal line;
[0032] Step 2, check the line connection, send a speed command 0 to the flywheel motor controller to test whether the flywheel control system communication is normal; if the flywheel control system returns a test response frame, it indicates that the communication is normal, perform step 3, if the flywheel control system If the system does not return a test response frame, it indicates that the communication is not normal. Check possible faults such as whether the test command is correct, poor line contact, disconnection, etc., and repeat step 2 until the communication is normal;
[0033] Step 3: Se...
