The way that motor works is that there is a capacitor that is used to make it spin in the correct direction, then once it gets to about 75% speed, a centrifugal switch on the motor opens up and cuts out the capacitor. Opening that switch creates an arc and the AFCI breaker is SUPPOSED to filter that out, but sometimes it doesn''t and it trips.

A capacitor will reach 63.2% of its full charge after just one time constant, which is calculated using the formula t = R*C. For a 99% charge, it takes 5-time constants. Generally, a capacitor is considered fully charged after 4 or 5-time constants. So, the charging time of a capacitor depends on its time constant and the desired level of charge.
Capacitors play a vital role in initiating the compressor''s operation. When the compressor struggles to start, the capacitor may attempt to draw a high current level during activation. If this current exceeds a specific threshold, it can cause the breaker to trip. Over time, capacitors can also deteriorate and lose their effectiveness.
It will occasionally be a reason to pass extra current over the loop and cause overload. Hence circuit breaker will trip the circuit for no reason. 4. Bad Capacitors. Capacitors are used across the motors to enhance the initial torque. If a motor having weak or exploded capacitor it will eventually have poor starting torque.
Cheaper GFCIs are susceptible to being "fooled" by capacitance in a circuit, and your AC induction motor looks to be a Capacitor Start at least, probably Cap-Start / Cap-Run, meaning there are multiple capacitors in it and the Run cap is always in the circuit. it takes a while for a capacitive charge to build up across the rotor and stator to ...
I removed the capacitor cover and the capacitor looked quite good but there was a very thin layer of red dust sort of like rust that was inside the cover and also on the part of the motor that was covered by the capacitor cover. Could this have come from inside the motor though the 1/2" hole the capacitor wire go through? If yes what would it be?
But depending on the type of failure in the capacitor, you will get different results. If it fails open, then spinning the blade by hand <<cringe>> might start the motor. If the capacitor shorts to itself internally or to ground (metal cased capacitor) the breaker will trip.

Take the belt off so there is no load on the motor and try turning it on. If the motor trips it could be a bad overload switch or a bad centrifugal switch but more likely a short in the windings. You would have to take the motor partially apart to check for a short but A quick test would be smell the motor if it smells burnt it''s shorted.
A permanent split capacitor motor, also known as a PSC motor, is defined as a split-phase induction motor with a capacitor permanently connected to enhance operation. A split capacitor motor is an AC motor. It is a type of single-phase induction motor. Similar to other AC motors, a split capacitor motor consists of a stator and a cage-type rotor.
