Abstract
The utility model provides a PMSM hoist mechanism, includes PMSM, stopper, reel, bearing frame, sensor and control system, and the reel is installed on the bearing frame, and its characterized in that, PMSM installs in the inside of reel, and the stopper is installed on the bearing frame, and passes through the axle hookup with PMSM. The control system controls the permanent magnet synchronous motor to directly output low-rotating-speed large-torque power to drive the winding drum to rotate so as to achieve the purpose of lifting heavy objects, and the brake is used for braking. The utility model discloses a PMSM hoist mechanism is small, light weight, high, the automatic integrated level of transmission efficiency good, operate steadily.
Description
Technical Field
The utility model relates to a hoisting equipment, especially a PMSM hoist mechanism.
Background
The conventional hoisting equipment structure (as shown in fig. 2) mainly comprises a driving motor, a speed reducer, a brake, a bearing seat, a winding drum, a speed position sensor and other components. The driving motor provides power, the speed reducer reduces the rotating speed, improves the torque and drives the winding drum to rotate so as to achieve the purpose of lifting heavy objects, and meanwhile, the brake is used for braking.
Along with the development of the industry in China, the hoisting equipment is more and more applied and has wider range, and the volume and the self weight of the hoisting equipment are gradually increased along with the increase of the hoisting capacity. Meanwhile, in many use scenes, due to the limitation of installation space and other reasons, the call for small volume and light weight of the hoisting equipment is stronger.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a small, light in weight, high, the automatic integrated level of transmission are good, operate steady PMSM hoist mechanism.
The utility model discloses a PMSM hoist mechanism, including PMSM, stopper, reel, bearing frame, sensor and control system, the reel is installed on the bearing frame, its characterized in that, and PMSM installs inside the reel, and the stopper is installed on the bearing frame, and passes through the axle hookup with PMSM.
The utility model discloses a PMSM hoist mechanism theory of operation is, by the big moment of torsion power of the direct output low rotational speed of control system control PMSM, drives the reel and rotates the purpose that reaches the promotion heavy object, and the stopper is used for the brake braking.
The utility model discloses a PMSM hoist mechanism compares the advantage of traditional hoist:
1. by adopting the permanent magnet synchronous motor, the output rotating speed of the motor is directly reduced, the size of the motor is greatly reduced, a speed reducer structure is cancelled, the weight is greatly reduced, a transmission chain is simplified, and the transmission efficiency is improved;
2. the permanent magnet synchronous motor is arranged in the winding drum, so that the size of the whole machine is greatly reduced, and the arrangement space of a hoisting mechanism is saved;
3. the control system adopts a special frequency converter for centralized control, and has the advantages of stable starting, running and stopping, no mechanical impact, no impact current and high automation integration level.
