Abstract
The utility model relates to a kind of steel rail grinding tramcar motor meeting two kinds of supply power modes, belongs to the steel rail grinding tramcar motor that can meet synchronous generator unit and inverter power supply.It mainly solves synchronous generator unit and powers full pressure when starting, and starting current is large, although inverter power supply starting current is little, and the problem that power quality is low.The utility model comprises stators and rotators, it is characterized in that: in stator core, the shape of the groove of embedding stator winding is a semi-closed port round bottomed vessel, be provided with corona-resistant insulation material between bottom stator winding and this semi-closed port round bottomed vessel, the flute profile in rotor core is a knife-edge groove.Motor of the present utility model is provided with the stator core of semi-closed port round bottomed vessel and the rotor core of knife-edge groove that can meet two kinds of supply power modes, inverter power supply is adopted during motor starting, Synchronous generator is adopted to power during long-term work, starting current can be evaded large, Harmonic Current fluctuation can be evaded again, improve motor useful life.
Description
Technical field
The utility model relates to and a kind ofly meets the steel rail grinding tramcar motor of two kinds of supply power modes, relates to one specifically and can meet and to power lower starting under no load at synchronous generator unit, can meet again the steel rail grinding tramcar motor of starting under no load under inverter power supply.
Background technology
At present, known rail grinding machine motor mode is powered by synchronous generator unit, and its advantage is that power quality is high, without harmonic disturbance, when shortcoming is the starting of full pressure, starting current is large, be about 7 times of rated current, the shortcoming such as easy scaling loss steel rail grinding tramcar motor during starting; Supply power mode adopts inverter power supply mode, its advantage to be started by low-frequency and low-voltage, starting current is little, not easily scaling loss steel rail grinding tramcar motor, shortcoming is that inverter power supply power quality is low, there is harmonic disturbance, during long-time running, reduce ageing of insulation intensity, reduce the useful life of steel rail grinding tramcar motor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide starting time adopt inverter power supply, being switched to Synchronous generator during long-time running powers, and meets the steel rail grinding tramcar motor of two kinds of supply power modes.
Technical solution of the present utility model is: motor comprises stators and rotators, it is characterized in that: in stator core, the shape of the groove of embedding stator winding is a semi-closed port round bottomed vessel, be provided with corona-resistant insulation material between bottom stator winding and this semi-closed port round bottomed vessel, the flute profile in rotor core is a knife-edge groove.
Stator winding in semi-closed port round bottomed vessel groove described in technical solution of the present utility model adopts frequency conversion enamelled wire.
The utility model is semi-closed port round bottomed vessel owing to meeting the rail grinding machine motor stator-core grooved of two kinds of supply power modes by design on steel rail grinding tramcar motor, rotor core grooved is knife-edge groove, stator winding adopts frequency conversion enamelled wire and corona-resistant insulation material to carry out satisfied adaptation two kinds of supply power modes, when steel rail grinding tramcar motor adopts inverter power supply when starting, adopt Synchronous generator to power when long-term work, the problem that starting current is large can be evaded, the problem of Harmonic Current fluctuation can be evaded again, significantly improve motor useful life.
