Description
Technical field
The invention belongs to the low-speed big permanent magnet motor technology scopes in magneto technical field, more particularly to answer
For one of mine equipment equipment small space low-speed big permanent magnet motor intelligence drive system.
Background technique
In the production equipments such as coal mine, harbour, mine, equipment installation space is often subject to limit, it is therefore desirable to provide small
A kind of drive assembly of the big torque of slow-speed of revolution in space, the market demand are larger.
For the problem, traditional solution is using threephase asynchronous, fluid coupling and speed reducer combination
Mode power drive is provided, since the revolving speed of threephase asynchronous is high, speed reducer needs the multi-stage speed-reducing could be by revolving speed
It is reduced to the revolving speed of needs, the deceleration mechanism for thus causing speed reducer is huge, and then the volume of speed reducer is made to become larger, and by
It is in threephase asynchronous detent torque little, it needs to increase fluid-flywheel clutch in order to meet the needs of bringing onto load starting and realizes
The soft start of motor, first allows motor no-load to start, then is driven and loaded by fluid-flywheel clutch.This method, which will increase to buy more, to be set
Standby investment, and structure is complicated for fluid coupling, and compared with common shaft coupling, fluid coupling is bulky, therefore increases
The operational reliability that fluid coupling will lead to unit is decreased obviously, and dramatically increases degree difficult in maintenance.
Therefore traditional to be solved in the form of moving load with high speed, large speed ratio multi-stage speed reducer, fluid coupling combination
The problem there are high revolving speed part, mechanical loss is big, transmission efficiency is low, noise is big, maintenance cost is high, asynchronous machine temperature rise
Greatly, relatively product is big, cost performance is not high for structure entirety body for high, energy consumption.
With the development of magneto technology, permanent magnet direct driving motor is also more and more applied in actual production, but
Its there are volumes it is big, weight is big, manufacturing cost is high the problems such as, cost performance is not high.Occurred half directly-drive permanent magnet motor power in recent years
Assembly, motor and speed reducer connection precision is more demanding, and speed reducer is semi-closed structure, and speed reducer lubricating oil is easily accessible
Inside motor, these lubricating oil for entering motor interior increase the power consumption of motor, while reducing the electrical of motor
Performance can make electric motor overheating, and motor may be burnt when serious.

Novel Sector-stator Motor with Low is small in size, light-weight, the energy-efficient, slow-speed of revolution, large torque, mechanical loss are small, operation expense
Low, good seal performance, safe and reliable purpose.
Summary of the invention
To overcome above-mentioned prior art defect, the present invention provides a kind of small space low-speed big permanent magnet motor driving
System.
It is of the present invention the specific technical proposal is:
A kind of small space low-speed big permanent magnet motor intelligence drive system, including low-speed big permanent magnet motor,
Speed reducer, high-power permanent magnet synchronous motor driver and host computer, the output shaft of the low-speed big permanent magnet motor with
The input axis connection and the casing of low-speed big permanent magnet motor and the casing of speed reducer of speed reducer are connected as one, institute
It states, the casing of the low-speed big permanent magnet motor is equipped with terminal box, the high-power permanent magnet synchronous motor driver
It is linked together far from low-speed big permanent magnet motor and by conducting wire and the terminal box, the host computer is big far from low speed
It torque permanent magnet motor and is linked together by conducting wire and the high-power permanent magnet synchronous motor driver, it is described high-power
Permasyn morot driver rated power >=55KW, servo motor are divided into AC servo and DC servo, wherein exchange is watched
Clothes are divided into synchronous and asynchronous again.Permanent magnet synchronous motor is exactly one kind of synchronous AC servomotor in fact.So-called permanent magnetism is same
Step motor is exactly not instead of coil or inductive material, permanent magnet on rotor, and controlling such motor will use special servo drive
Dynamic device, the permasyn morot driver are a kind of servo-drivers of special driving low-speed big permanent magnet motor,
It is mainly used for controlling and adjusting the speed and torque of three-phase ac synchronous motor.The permasyn morot driver uses high property
The vector control technology of energy, low-speed high-torque output are used as control core using digital signal processor (DSP), may be implemented
More complicated control algolithm realizes that digitlization, networking and intelligence, power device are generallyd use with intelligent power module
It (IPM) is the driving circuit of core design, IPM has been internally integrated driving circuit, while having overvoltage, overcurrent, overheat, owing
Circuit is protected in the fault detections such as pressure, is additionally added soft starting circuit, in major loop to reduce impact of the start-up course to driver.
Power drive unit passes through three-phase bridge rectification circuit first and rectifies to the three-phase electricity or alternating current of input, obtains corresponding
Direct current drives three-phase forever through the good three-phase electricity of over commutation or alternating current, then by three phase sine PWM voltage source inverter frequency conversion
Magnetic-type synchronous AC servo motor, the whole process of power drive unit can briefly be exactly the process of AC-DC-AC, whole

Gear and contain it body size and weight, furthermore speed reducer it is totally-enclosed refer to processing is sealed to speed reducer, subtract
Fast device need the position sealed generally have at axis stretching, on the inside of bearing chamber, cabinet joint surface and bearing cap, inspection hole and outage
Joint surface etc., sealing means can be divided into contact seal and non-contacting seal, for contact seal, and can be divided into
Two kinds, wherein based on hair felt-ring seal and cup packing, non-contacting seal, the principle for mostly using space to be isolated greatly, wherein
Including clearance seal box labyrinth sealing, the furthermore sealing of case lid and block joint surface applies close on case lid and block joint surface
Sealing sealing is the most universal, also there is on block joint surface while opening oil return ditch, and the oil between penetrating into joint surface is allowed to pass through oil return ditch
And back oil road flows back in case that oil sump is to increase sealing effect, the sealing at other positions, access plate, oil drain plug, oil ga(u)ge with
It is both needed to add paper oil sealing pad or skin oil seal ring between the joint surface of cabinet.Encryption gasket is needed between screw-type bearing (ball) cover and cabinet,
The rubber seal rings for seal leakproof of O shape is commonly used between insert bearing end cap and cabinet, using the lubrication in speed reducer after encapsulation process
Oil will not seal in motor perhaps in atmosphere while also can make speed reducer under water or flammable explosive gas with air exclusion
Middle work improves certain safety.
As another improvement of the invention, the low-speed big permanent magnet motor is turned using embedded rare earth permanent-magnetic material
Minor structure, rotor and stator lack slot cooperation using multipole, and compared with traditional permasyn morot, multipole lacks slot permanent-magnet synchronous
Motor have the advantages that traditional synchronous permanent-magnet motor it is shared outside, have the further advantage that multistage magnetic circuit arrangement reduces
The magnetic yoke of motor, the weight saving of motor, coil spread are equal to slot pitch, and winding overhang shortening has been saved copper material, reduced
Copper loss improves efficiency, and motor is small in size, and the torque that unit volume generates is big, improves radiating condition.
The positive effect of the present invention is: realize Novel Sector-stator Motor with Low is small in size, light-weight, the energy-efficient, slow-speed of revolution,
Large torque, mechanical loss are small, operation expense is low, good seal performance, safe and reliable purpose.
