Three-phase motor has a multiple of 3 slots. A slot represents the number of coils of fixed stators.Three-phase motor is a motor with three independent coils at 120 degree intervals. The phase represents the number of independent coils for fixed stators.(From the viewpoint of motor control, when the number of poles is doubled, the speed will be halved, and when the number of poles is quadrupled, the speed will be quartered, therefore the control method does not depend on the number of poles.) The number of poles can be 2, 4, 6, 8., etc. The pole represents the number of permanent magnet poles for the rotating rotor, and a motor with one pair of N pole/S poles is called a two-pole motor.Volatility for a slot is calculated in a scale of Low-High with varying degrees of hit rate for each slot. When the number of poles and the number of slots increases, a large torque can be obtained and the torque pulsation also decreases. Volatility dictates the average win rate of a slot and is also linked to the expected level of return on a given win. There are various combinations such as 4-pole 3-slot, 4-pole 6-slot, and 16-pole 12-slot. The most basic 3-phase brushless motor is a 2-pole 3-slot motor. 3-phase motors are a common type of motor.
