The invention provides a four-pole energy-saving escalator driving motor, which comprises a stator iron core and a rotor iron core, a plurality of iron core grooves are annularly and uniformly distributed on the stator iron core, and stator windings are arranged in the iron core grooves; the rotor core is coaxially and rotatably sleeved in the stator core, an air gap is arranged between the rotor core and the stator core, and the center of the rotor core is provided with a shaft hole; the rotor core is provided with four magnetic poles, and each magnetic pole is provided with a magnetic barrier structure and a magnetic bridge structure. Compared with a traditional three-phase asynchronous motor, the synchronous reluctance motor has the advantages that no winding, no aluminum casting and no rotor loss are arranged on the rotor, the motor efficiency is improved, the energy consumption in the manufacturing link is greatly reduced, no permanent magnet is arranged on the rotor, the cost is lower, the problem of high-temperature demagnetization does not exist, the synchronous reluctance motor can stably run at high temperature, and the service life of the synchronous reluctance motor is prolonged. The long-term use efficiency is more stable.
