The invention relates to a permanent magnet synchronous direct-drive lifting machine with a gear. A built-in multi-disk braking permanent magnet motor as a prime motor to drive a drum of the lifting machine to rotate; the inner wall of the drum is provided with an inner gear ring; a driving output gear of a drum driving device is meshed with the inner gear ring of the drum; a multi-disk braking device is arranged in the rear portion of a rotor of the built-in multi-disk braking permanent magnet motor; a braking disk combination is pushed by a braking elastic device to form braking during non-energization; the braking force applied to the braking disk combination due to the braking elastic device is relieved through a gate opening power device after energization. According to the permanent magnet synchronous direct-drive lifting machine with the gear, the weight is light, the size is small, the speed adjustment range is wide, the operation and the control are convenient, the use is safe and reliable, and the manufacturing cost and the operation cost can be significantly reduced.
