Description
Technical field
The present invention relates to the frequency conversion motor for locomotive, belong to technical field of motors.
Background technology
Current domestic frequency conversion motor or Y/Y2/Y3 center height, at the motor of 280, do not have the standard of 10 poles, owing to its space structure is nervous, are unfavorable for the rotor flux space conversion of motor；With the motor of power grade, 10 pole motor torques are big；This motor can realize the change that velocity interval is bigger.
Summary of the invention
It is desirable to provide a kind of PWM inverter-fed traction motor for locomotive, it is intended to meet the requirement of small size, on a large scale speed governing；Have that speed governing is easy, energy-conservation, simple in construction, easy to control, safeguard easily, the advantage such as cost is low.
In order to achieve the above object, the present invention provides a kind of PWM inverter-fed traction motor for locomotive, including stator and rotor；Described stator includes that iron core, coil and support, described stator are arranged in casing；Described rotor includes iron core and coil；Described rotor is sleeved on output main shaft；Described main shaft is sleeved in casing by two rolling bearings；Described casing is provided with radiating ribs；Described casing is positioned at below enclosing cover and is provided with velometer gear, and described velometer gear, with teeth groove, is sleeved on described main shaft；Described enclosing cover is fixed on end cap by uniform fastening bolt；Additionally, described casing is positioned at outside described main shaft the bearing shell being provided with for connecting locomotive.
Furthermore it is preferred that under mode, described radiating ribs is positioned in the described casing of described laundry setting.Described bearing shell is provided with the positioning element for connecting locomotive and fixed component.
It is easy, energy-conservation that the present invention has speed governing；Absence of commutator and brush, simple in construction, easy to control, safeguard that easily cost is low；Capacity can be expanded, it is achieved subnormal voltage operation；Soft start and fast braking can be realized；No-spark, the advantages such as adaptive capacity to environment is strong.

Detailed description of the invention
A kind of PWM inverter-fed traction motor for locomotive, including velometer gear 1, end cap 2, main shaft 3, stator 4, rotor 5, end cap 6, radiating ribs 7, enclosing cover 8, casing 9, bearing shell 10.Stator 4 of the present invention and rotor 5, in the least space, complete 10 pole electric machine rotor flux space conversions.Specifically, rotor is made up of iron core, coil or sliver, rotating shaft, and rotor is sleeved on main shaft, is integrally forming with main shaft；Stator 4 is mainly made up of iron core, coil and support, and stator is arranged in casing 9；Radiating ribs is had in casing 9；Enclosing cover 8 is fixed on end cap 2 by uniform fastening bolt；Main shaft 3 is sleeved in casing 9 by two rolling bearings.Being provided with velometer gear 1 below described enclosing cover 8, velometer gear is sleeved on electric machine main shaft with teeth groove, velometer gear 1.Equipped with bearing shell 10 in casing 9, installed with locomotive by bearing shell.There is a heat radiation gusset 7 upside of casing.
The teeth groove variable signal of the velometer gear of the present invention, by the transmitter on locomotive, is transported to converter signal after being converted into the signal of telecommunication, again to adjust motor speed；End cap is the support member of rotating part, in order to lay bearing and measure speed gears；These parts also act as the effect of protection stator and rotor；Stator is mainly made up of iron core, coil, support etc., and the threephase AC electric energy inputted by converter, by current-carrying part coil and permeable section iron core, is converted into rotating excitation field；Rotor main to be made up of iron core, coil or sliver, rotating shaft etc., and this rotary part is the significant components converting electric energy to mechanical energy；Enclosing cover is in order to support and to protect encoder velocity sensor.
A kind of specifically used locomotive frequency conversion motor of the present invention, power 22kW, rated voltage 380V, rated current 51A, rated frequency 50Hz, rated speed 589r/min, efficiency 89%, class of insulation H.Motor case is with bearing bush structure.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope of present disclosure; according to technical scheme and inventive concept equivalent or change in addition thereof, all should contain within protection scope of the present invention.
