The motor comprises a motor flame-proof outer casing and a stator arranged inside the outer casing, wherein the outer casing is formed by a motor base and end covers fixed at two ends of the motor base. The motor is characterized in that a synchronous rare-earth permanent magnet rotor with a rare-earth magnet is installed inside the motor base; the rare-earth permanent magnet rotor is connected with a position monitor; and a temperature sensor is arranged inside the stator. The motor has the advantages of simple structure, reliable work, long service life, high electricity-saving quantity, large attractive force, easy maintenance and repair and the like, and is simultaneously suitable for being used under the high-gas conditions of underground coal mines and other conditions with hazardous gas.
Description
Technical field
The utility model relates to a kind of motor of new structure, is specifically related to a kind of flame-proof mine permanent-magnet synchronous traction motor.
Background technology
Mining narrow gauge DC power supply electric locomotive or other driving motors of China's coal-mine mostly adopt DC motor and AC asynchronous motor at present.
Though DC motor has advantages such as good speed adjustment features, but traditional DC motor adopts brush-commutator structure, there are a lot of drawbacks, as: 1) power consumption is big, the efficient of DC traction motor is lower, DC motor mostly adopts rheostatic speed regulation or chopping regulating speed simultaneously, is difficult to accomplish the energy feedback in the motor braking process, so DC traction motor energy consumption in being applied to storage battery or stringing electrical locomotive is big.2) maintenance amount is big, and the brush-commutator of motor often damages, and needs frequent M R, the waste lot of manpower and material resources.3) DC motor life-span weak point, because copperhead commutator and carbon brush that DC motor must have, this just must cause the easy damage of DC motor, useful life is short.
That AC induction motor has is simple in structure, reliable operation, life-span are long, easy advantage such as maintenance; but shortcoming such as have that operational efficiency is low, speed adjusting performance is undesirable, overload capacity is poor, power factor (PF) is low and salvo is not enough can start difficult even burns out because load is excessive.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of flame-proof mine permanent-magnet synchronous traction motor is provided, this motor adopts has the synchronous rare-earth permanent magnet rotor of rare earth magnet, and position monitor, temperature sensor be set in motor, have that power factor (PF) height, operational efficiency height, staring torque are big, high reliability, advantage such as maintenance workload is little and the life-span is long, have explosion prevention function simultaneously, the mine or the association area that are suitable for dangerous gas are used.
The utility model purpose realizes being finished by following technical scheme:
A kind of flame-proof mine permanent-magnet synchronous traction motor, include the motor explosion-resistant enclosure and be arranged at described shell internal stator, described shell is made up of motor bed-plate and the end cap that is fixed in described motor bed-plate both ends, it is characterized in that: the synchronous rare-earth permanent magnet rotor with rare earth magnet is housed in the described motor bed-plate, described rare-earth permanent magnet rotor is connected with position monitor, is provided with temperature sensor in the described stator.
Described shell upper is provided with wire connection cavity, and the holding wire of described position monitor, temperature sensor links by binding post and wire connection cavity.
The utility model has the advantages that:
1) hauling ability is better, and when low-frequency starting, starting torque is big, can make AC permanent-magnet sync pulling motor meet or exceed the starting torque and the pulling figure of direct current machine.Satisfy being pulled the maximum starting tractive effort of object when low speed, make the band heavy-load start strong and powerful.
2) maintenance capacity is littler, and permanent-magnetic synchronous motor rotor does not have coil and commutation copperhead, and the maintenance load of motor itself is very little.
3) it is high a lot of that saves energy, direct current machine that efficient is more traditional and asynchronous machine are obviously wanted, and under the braking situation of motor use, motor can be realized the energy feedback by controller simultaneously.
4) life-span long, motor contains functions such as temperature detection, can realize but motor can reduce the power operation when surpassing self design limit or shut down by motor controller, effectively protects motor, thereby can prolong the useful life of motor greatly.
