直线电动机（Linear motor） General motors work are rotation. But driven by the rotation of the motor vehicle (such as motor cars and city trams etc.) need to do linear motion, some parts driven by the rotation of the motor of the machine to do linear motion. It is necessary to increase the rotary motion into a linear motion device. Can directly use the linear motion of the motor to drive, thereby eliminating the need for this suit? This problem has been raised a few decades ago and has now been made into a linear motion motor, a linear motor 1 working principle A linear motor is a device that converts electrical energy directly into mechanical energy in a straight line without any intermediate switching mechanism. It can be thought of as a rotating motor that is cut radially and expanded into flat surfaces The side that evolved from the stator is called the primary, and the side that is evolved from the rotor is called secondary. In practical applications, the primary and secondary parts are manufactured in different lengths to ensure that the coupling between the primary and the secondary remains the same in the required range of travel. A linear motor may be short, primary, long, secondary, or long, primary, short, secondary. In view of manufacturing costs and operating costs, short primary, long and secondary are generally used. The working principle of a linear motor is similar to that of a rotating motor. The linear induction motor for example: when the primary windings of AC power supply, will produce traveling wave magnetic field in the air gap in the secondary cutting under traveling magnetic field, the induced electromotive force and current, the current and the air gap magnetic field is generated electromagnetic force. If the primary is fixed, the secondary is subjected to a linear motion under thrust; conversely, the primary is subjected to linear motion. The principle of linear motor is not complicated. The idea of an induction motor rotation along the radius d
