The invention discloses an ultrathin permanent magnet synchronous host with a preposed encoder. The ultrathin permanent magnet synchronous host comprises a synchronous motor, a reduction gearbox, an encoder and a brake, the synchronous motor is mounted in a moving track of escalator steps or pedals; the reduction gearbox is positioned between the steps on two sides or pedal driving chain wheels; an output shaft of the synchronous motor is vertically connected with the input end of the reduction gearbox; a mounting box is arranged on the outer side, far away from the synchronous motor, of the reduction gearbox; the encoder is arranged in the mounting box, the output shaft penetrates through the reduction gearbox and extends into the mounting box to be connected with the encoder, a driving shaft is arranged between the driving chain wheels, the output end of the reduction gearbox is connected with the driving shaft, and the brake is arranged on the side, away from the reduction gearbox,of the synchronous motor. The encoder is arranged in a front-arranged mode, the concentricity and the anti-interference capacity of the encoder are enhanced, and the encoder is not affected by the installation mode of the brake and a magnetic field; in addition, the encoder is mounted in a front-arranged mode, disassembly and overhaul are convenient, and later maintenance is facilitated.
