About motor insulation
Dielectric loss of insulating material
The electric field intensity increases. The loss tangent also increases. When the voltage increases to a certain value, the bubbles inside the medium or the edge of the electrode will be partially freed, and the loss tangent suddenly increases significantly. This voltage value is called the initial free voltage. In engineering, the initial free voltage measurement is often used to check the air gap in the insulation structure to control the insulation quality.
In addition, some insulating materials should also consider electrical properties such as corona resistance, arc resistance, and resistance to leakage traces.
The electrical performance requirements of the motor for the insulating material are the breakdown electric field strength and the insulation resistance as the most important. Depending on the type of motor, other electrical performance requirements are not exactly the same. For example, the insulation of high-voltage motors requires low dielectric loss of the insulating material and good corona resistance; and the electric field distribution between the iron core and the conductor must be considered.
