FAQ

1. The stator remains unchanged, what are the effects of the number of rotor slots on the performance of the motor?
   The rotor slot shape determines the resistance value of a single rotor slot, which is related to the number of slots to comprehensively evaluate the overall trend of the rotor resistance changing with the slot size. That is to say, we are going to discuss the topic of the number of rotor slots today.
   
   Compared with the stator part, the geometrical space of the rotor slot shape and the number of slots is relatively limited. On the premise of satisfying the starting performance, the minimum leakage reactance of the rotor is taken as the best combination of the number of rotor slots and the matching of the slot shape, and the ideal maximum torque can be obtained at the same time.
   
   When the number of rotor slots increases, the slot shape of the motor becomes narrower and longer, the slot leakage reactance increases, and the ratio of the leakage reactance current in the reactive current to the excitation current increases, resulting in a large current during rated operation, an increase in resistance loss, and an increase in power loss. Factor indicators deteriorate and efficiency decreases. In addition, because the effect of the skin effect is also enhanced as the slot shape becomes narrower and longer, the rotor resistance becomes larger, and the rotor loss also tends to increase, adding another factor of poor efficiency.
   
   In fact, the efficiency, power factor of the motor and the number of rotor slots also have an optimal fit point. In addition to the influence of the stator and rotor slot coordination on starting, noise and vibration, the selection of the number of rotor slots in the design should comprehensively consider the operating performance and Correlation of the number of rotor slots.
   
   The rotor slot of the motor can adopt many types such as round bottom type, flat bottom type, pear type and trapezoid. A large number of data statistics and analysis have found that different groove shapes have different influences on motor performance: flat-bottomed grooves are more conducive to improving motor efficiency, while pear-shaped grooves are conducive to improving motor power factor, but all of this is based on a certain Fixed number of rotor slots.
   
   The actual design process of the motor is generally based on a relatively fixed stator, and the most ideal performance indicators are obtained by calculating and simulating the number of rotor slots by transforming and adapting. For the design under the condition of controllable power supply, the degree of freedom in selecting the number of slots is greater, so the space for motor performance optimization will be relatively loose.
