Abstract

The utility model relates to a motor, particularly relating to a permanent-magnet synchronous motor and in particular relating to a flameproof direct-drive permanent-magnet synchronous motor which can directly drive a screw-pump oil pumping unit in an oil field, solving the problem that currently no motor can directly drive the screw pump of an oil pumping unit in an oil field. The flameproof direct-drive permanent-magnet synchronous motor comprises a stator and a rotor, and the rotating shaft of the rotor is a hollow shaft provided with an internal spline. The flameproof structure of the flameproof direct-drive permanent-magnet synchronous motor adopts a flameproof structure at Exd II BT4 flame resisting level. When the permanent-magnet synchronous motor is in use, the internal spline of the rotating shaft of the rotor directly matches with an outer spline shaft of the screw pump to transfer the torque, so that the screw pump can be directly driven by the motor. The permanent-magnet synchronous motor can be dispensed with a retarding mechanism and can directly drive the screw pump. Therefore, the permanent-magnet synchronous motor remarkably improves the efficiency of the system, achieves the effects of protecting the environment and saving energy, simplifies the system and reduces the cost of the whole device.

Description

Flame-proof type direct-drive permanent-magnetism synchronous motor
Technical field
The utility model relates to motor, and particularly permanent magnet synchronous motor is specially the flame-proof type direct-drive permanent-magnetism synchronous motor that is used for oil-field oil pumper.
Background technology
Oil field screw pump oil pumper, its screw pump is by motor driven.The driving mechanism of oil field screw pump oil pumper is that asynchronous machine adds belt pulley, gear box reducing gear etc. at present, complex structure, and efficient is low, the failure rate height.
Summary of the invention
The utility model provides a kind of flame-proof type direct-drive permanent-magnetism synchronous motor in order to solve the problem of the motor that does not have directly to drive oil field screw pump oil pumper at present.This flame-proof type direct-drive permanent-magnetism synchronous motor can directly drive the oil-field oil pumper screw pump.
The utility model is to adopt following technical scheme to realize: flame-proof type direct-drive permanent-magnetism synchronous motor, comprise stator and rotor, and the rotating shaft of rotor is the internal spline hollow shaft.Because the internal spline hollow-core construction has been adopted in the rotating shaft of rotor, directly mate (male splined shaft of screw pump penetrates in the hollow rotor shaft of internal spline) transfer torque during use with the male splined shaft of screw pump, and the realization motor is to the direct driving of screw pump.
Flame-proof type direct-drive permanent-magnetism synchronous motor described in the utility model adopts the internal spline hollow-core construction by the rotating shaft of rotor, realized direct driving, filled up the blank that does not have directly to drive oil-field oil pumper screw rod pump motor at present the oil-field oil pumper screw pump.Adopt this motor can remove reducing gear, directly the drive screw pump significantly improves system effectiveness, realizes energy-conserving and environment-protective, and simplified system reduces the integral device cost.Its structural design novelty, ingenious, reasonable.
Description of drawings
Fig. 1 is the structural representation of flame-proof type direct-drive permanent-magnetism synchronous motor described in the utility model;
Embodiment
Flame-proof type direct-drive permanent-magnetism synchronous motor comprises stator and rotor, and the rotating shaft 1 of rotor is the internal spline hollow shaft.During concrete the manufacturing, the rotating shaft 1 of rotor is a rectangle internal spline hollow shaft, and promptly the inner chamber spline-shaped of hollow rotating shaft is a rectangle, and correspondingly the external splines cross section of screw pump also is a rectangle.Because this permasyn motor direct connects the screw pump that drives oil-field oil pumper, so its installation site (vertical installation) be located immediately at well mouth of oil well, so the motor explosion insulation performance is had relatively high expectations.The explosion separation structure of this permanent magnet synchronous motor adopts the desired explosion separation structure of ExdIIBT4 flame proof grade.This permanent magnet synchronous motor is by rational Electromagnetic Design, structural design, make it have the performance of high efficiency, High Power Factor, high power density, the occasion of operation also was specially adapted to oil-field oil pumper when therefore this motor was particularly suitable for low speed high torque, permanent torque varying frequency starting, length.
