Motor mounting structure with electromagnetic induction type rotary transformer

Abstract

The invention provides a motor mounting structure with an electromagnetic induction type rotary transformer. The motor mounting structure comprises a motor body, the electromagnetic induction type rotary transformer and a motor controller module, wherein the electromagnetic induction type rotary transformer is connected with the motor body, and is used for outputting a coding signal; and the motorcontroller module is used for receiving the coding signal and controlling the motor body. Compared with the prior art, the motor mounting structure with the electromagnetic induction type rotary transformer has the following advantages that 1) the mounting modes of the motor are diversified and simple, and installation in a shaft penetrating manner, a shaft end manner and a shaft side edge mannercan be realized; 2) a non-contact induction mode is adopted, so that the service life is long; 3) the structure is anti-jitter, oil-resistant and anti-electromagnetic interference and high in high-temperature resistance and high in low-temperature resistance; and 4) an output signal form can be adapted to any motor controller interface.

Description

Technical field [0001] The invention relates to a motor mounting structure with an electromagnetic induction type resolver. Background technique [0002] The concept of Industry 4.0 is being widely spread around the world, which represents the future development trend of intelligent industry, and in the new generation of motor manufacturing, fast and efficient is the clear trend of technological development. The requirements for motor control in more and more applications and fields have not only stopped at the general-purpose inverter and speed control that meet energy-saving requirements, but precise position control has become a new demand point. [0003] Motor position detection and feedback are completed by the motor position encoder, so an excellent motor position encoder largely determines the performance of the motor in terms of energy saving, high efficiency, precision and interoperability. The current motor position encoder solutions on the market mainly include: [0004]...

AI Technical Summary

Problems solved by technology

[0006] Defects: The grating disk is fragile, easily polluted by oil and dust, resulting in signal loss, poor anti-jitter ability

[0009] Defects: The demagnetization of the magnet at high temperature causes the signal accuracy to decrease; the magnet magnetization technology requires high requirements, especially the uneven magnetization at the junction of the N and S poles leads to distortion of the sine wave signal, and the output signal accuracy decreases; the installation accuracy is high and the shock resistance is poor; only Can be installed at the end of the motor shaft

[0012] Disadvantages: The traditional resolver is large in size and weight, requires a large installation space, and causes troubles to the overall design of the motor

[0013] The above schemes have different degrees of defects in terms of motor installation methods, etc.
