Abstract
Disclosed is a dual-sensing feedback and transmission system for a linear motor. The system includes a linear motor, a transmission mechanism, and a dual-sensing displacement detection mechanism. One end of the transmission mechanism is fixedly connected to a mover of the linear motor, and the other end thereof is located outside a stator of the linear motor and fixedly connected to a leaf of a multi-leaf collimator directly or by means of a connecting block. The dual-sensing displacement detection mechanism is a dual-sensing linear displacement sensor, and includes two sets of reading devices for reading displacement information, and a matching reference ruler. The reading devices are fixed to an end or exterior of a casing of the stator of the linear motor close to the leaf of the multi-leaf collimator. The reference ruler is fixed onto a connecting rod.
