Embodiment Construction

[0017] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0018] figure 1 Middle is the schematic diagram of the winding skeleton of the present invention. The two-phase windings are separated through the partition in the middle of the winding frame. The winding frame is integrally molded with polyhexamethylene adipamide containing 30% glass fiber, which can maintain strong strength and rigidity at relatively high temperatures, and has low viscosity and good fluidity.

[0019] Such as figure 2 As shown, the driving circuit includes a power input, a protection circuit, a rectifying circuit, a voltage stabilizing circuit, an amplifying circuit, a winding and a trigger circuit for controlling forward and reverse junction field effect transistors, and a winding is arranged between the two windings. protect the circuit. After the power supply is input into the circuit, through the protection circuit, rectification circuit an...

Abstract

The invention relates to a DC brushless motor, and especially relates to an EC dual-winding DC brushless motor. The technical problem to be solved is that when the existing EC motor works at high temperature (above 30 DEG C), the phenomenon of inter-phase winding breakdown may easily happen, thus causing motor failure. The EC dual-winding DC brushless motor comprises a winding frame and a driving circuit; the driving circuit comprises a power input, a protection circuit, a rectifier circuit, a voltage stabilization circuit, an amplification circuit, a winding, and a trigger circuit of a junction type field effect transistor controlling forward-backward rotation; and the winding portion of the winding frame is provided with an isolation wall which divides the winding frame into two parts, and two phase windings are respectively wound on the two ends. The beneficial effects are that when the two phase windings are separated, the EC dual-winding motor can be used at high temperature, and the windings are hard to break down; and the improved driving circuit can eliminate high voltage generated by the two phase windings wound separately.

Description

technical field [0001] The invention relates to a DC brushless motor, in particular to an EC double-winding DC brushless motor. Background technique [0002] Among all kinds of servo motors, the DC motor has the best performance. It has small size, high efficiency, large output, large starting torque, good dynamic performance and convenient control. Therefore, in high-precision, high-performance servo control systems, DC motors are often used as driving actuators. Brushless DC motor is a new type of DC motor that replaces brushes and commutators with electronic reversing switches and position sensors. It consists of three parts: controller, rotor position detection and motor body, and is the product of the close combination of electronic technology and motor technology. It has the characteristics of high efficiency, wide speed range, quick start, good mechanical characteristics and adjustment characteristics, long life, convenient maintenance, high reliability, low noise, ...
