Linear motor direct drive with the advantages of simple structure, fast dynamic response, high precision, high speed, big acceleration, small noise and vibration, is the ideal transmission for all kinds of ultra-high speed and precision machine tool. This paper introduces the working principle and performance features of linear motors, and elaborates on the key technology problems and the solution countermeasures of seven aspects including the efficiency and the power factor, the cooling measure, the normal magnetic attraction, the servo-control, magnetism isolation and the protection, the gravity acceleration and the supply voltage of the linear motor.
