Discussion on motor resolver (1)

The sensor as a sensing device plays an absolute role in the control. Reminiscent of motor controller, it generally contains temperature sensor, currentvoltage sensor, and is directly related to the electric control The motor also has a position sensor, which is what we often call a resolver, or res

Discussion on the working principle of resolver (2)

Continue to talk about the rotation. In the previous article, we learned about Ampere's law and Faraday's law of electromagnetic induction. Two new terms are introduced today: Hall effect and magnetoresistance effect. 01.Hall effect and magnetoresistance effectMagnetoresistance The definition of Mag

Key Points of Winding in Manufacturing Process of High Frequency Transformer

A、Determine the parameters of BOBBINB、All windings are required to be flat and non-overlapping.C、A single set of winding wires can be single-color wires, and double-set winding wires must be divided into two-color wires or open wires soaked in tin to avoid wrong windingD、The

High Frequency Transformer Design Principles

When designing a high frequency transformer, the leakage inductance and distributed capacitance of the transformer must be minimized, because the high-frequency transformer in the switching power supply transmits a high-frequency pulse square wave signal. During the transient process of

What is a high frequency transformer

High-frequency transformer is a power transformer whose working frequency exceeds intermediate frequency (10kHz). It is mainly used as high-frequency switching power transformer in high-frequency switching power supply, and also used as high-frequency inverter in high-frequency inverter po
