Inverse magnetic axis complex line spiral tube type bidirectional balance-responding device

The invention relates to an inverse magnetic axis complex line spiral tube type bidirectional balance-responding device, which is also known as a linear motor. The inverse magnetic axis complex line spiral tube type bidirectional balance-responding device is mainly formed by passing a provided magnetic guide shaft through a channel of a group of coils, and the maximum proportion value of coil length to extension length is 15:7. The commonly used mode of the inverse magnetic axis complex line spiral tube type bidirectional balance-responding device is to operate at a rated coil current value, and a direct current and a non-direct current are both feasible. When the direct current is used, the magnetic guide shaft automatically extends to the maximum value when not loaded, and the extension direction is determined along with the current direction; the relative move position of the guide shaft and the channel is represented by a forward function of the current value when loaded, and the linearity is good; and the guide shaft automatically slides in a circulated manner when using the non-direct current. When in operation, the guide shaft and the channel have a certain suspension sliding property. The inverse magnetic axis complex line spiral tube type bidirectional balance-responding device is suitable for automatic support, continuous automatic positive and inverse slide, various force measurement, displacement control, robot movable devices and the like.
