This introduction provides a comprehensive overview of the MHD093C-058-NP0-BA motor, highlighting its key features, application scenarios, and technical parameters.

Increase the voltage

In the form of energy conversion in the motor, the loss of electrical energy is manifested as copper loss,

and its influencing factors includecurrentandresistance. If the designer finds that the copper loss is too large,

the simplest solution is to increase the working voltage. For example, for a motor with an input power of 500W,

if its working voltage is 10V, it means that the current must be 50A, because the input power is the product of voltage

and current. However, if we increase the voltage to 100V, the current only needs to be 5A. Since the relationship between

copper loss and current is quadratic, the copper loss will be reduced by 100 times after the voltage is increased.

This also explains why the working voltage of recent electric vehicles tends to develop to 800V.

Improve the slot utilization rate of ****

When it is not possible to increase the voltage, we often need to find ways to reduce the resistance.

The most straightforward strategy is to increase the cross-sectional area of the conductor. In the field of motors,

this has led to discussions on how to improve slot fill factors, and has resulted in new technologies such as

flat angle winding wires, which are varnished wires designed to achieve the goal of improving motor efficiency.
