Increase the motor scale

However, when we are unable to increase the slot filling ratio by means of production technology, we may choose to scale up the size of the

motor as a strategy. This not only provides a larger slot space to accommodate the enamel coil, but we also know from the torque formula of

the motor that there is a square relationship between the rotor diameter and the torque. For example, if the rotor diameter is increased from

50 to 60, although the diameter only increases by 1.2 times, the torque will increase by 1.44 times. If we maintain the same torque, this means

that we can reduce the current by 1.44 times, thereby reducing the copper loss. Therefore, scaling up the motor size can significantly contribute

to efficiency improvement. However, this also means that it will increase the material cost and storage and transportation cost, which may not be the best choice in thecommodification process.
