This is a synchronous motor, whose speed is determined by the frequency of the power supply. If there are no blades installed, the speed is also 100 rpm. If more blades are installed, the load is too heavy and the motor cannot start. The spring keeps repeating to help start

1. Add some lubricating oil to the bearings

Replacing the capacitor can definitely solve the problem

Additionally, slow speed does not necessarily indicate a capacitance issue, as capacitance ensures that the fan can rotate in the predetermined direction. Check the coils and bearings for any issues. Check if the fan blades are deformed. If the wind surface decreases, it will affect the air volume. Also, check if the speed controller has poor contact and keeps the gear in the low position,

There are generally only two ways to adjust the speed of ceiling fans, each with its own advantages and disadvantages: 1. The principle of autotransformer speed adjustment is simple and durable, but the speed between gears sometimes cannot be satisfactory. The speed changes significantly with voltage changes and consumes electricity. 2. Silicon controlled speed regulation can achieve no speed regulation, but it needs to be turned to a higher position during startup and can only be reduced to the required speed after startup, and it is not as durable as an autotransformer.
