Permanent magnet speed regulation device is generally used for blower fan, load of the pumps, has：Light-load starting, overload protection, slow down impact and every
The advantages that from shake is turned round；Because blower fan, load of the pumps have the shaft power characteristic directly proportional to the cube of rotating speed, i.e. rotating speed reduces
Afterwards, shaft power declines in cube, therefore permanent magnet speed regulation device is applied on such load machinery, can effectively change " big horse traction
The backwardness kind of drive of dolly ", energy-saving effect are notable.
Existing permanent magnet speed regulation device is to rotate the rotating excitation field to be formed and solid conductor or bulk using p-m rotor
Caused Lorentz force realizes the motion transmission between engine and working machine when conductor mutually moves.Due to solid conductor or
Bulk conductor when cutting the p-m rotor magnetic line of force caused induced current be conductor vortex, when its be used for blower fan,
During load of the pumps speed governing, because slip increases, therefore caused vortex also increases, now except a part is vortexed for producing biography
Lorentz force needed for dynamic system, remaining major part is idle work, and due to can not draw this partial vortices, therefore it can only
Consumed in solid conductor or bulk conductor in the form of heat；Although power output during above-mentioned permanent magnet speed regulation device speed governing
Decline with the cube of rotating speed, but caused heat is still larger, therefore born at present under the conditions of air cooling for blower fan, water pump class

Water cooling is still needed to, and cooling water easily produces corrosion to permanent magnet, copper dish (set) and iron yoke, it severe compromise is present；And
After cooling water temperature raises, it is also easy into the bearing at its both ends, emulsification of lubricant is gone bad, produces drive failures.
Existing permanent magnet speed regulation device typically makes the spline of conductor or PM rotor on power transmission shaft by speed adjusting gear
Pair is moved left and right to change axially or radially magnetic flux area, now needs to overcome two kinds of axial forces：1. magnetic caused by air-gap field
Pulling force axial component；2. frictional force when being moved along spline pair between splined shaft and splined hole.When both axial forces make band load
The torque of splined shaft transmission is very big, conductor (or permanent magnet) rotor is produced very big normal pressure in spline secondary surface, therefore
Rotor required frictional force overcome when being moved on spline pair is also very big.Assuming that ignoring the first axial force, and only consider
Two kinds of axial forces, then when transmit power be 100kW, rotating speed be 1000rpm when, the torque of spline pair transmission is 955Nm；Work as transmission
When the diameter of axle of axle is 100mm, its normal pressure formed is 19100N, and the required frictional force overcome is about 1910N, therefore frequently
Spline pair easily wears and causes speed adjusting gear not work during speed governing.

Operation；When carrying out rotational speed regulation, probe of contactor K1 is disconnected, probe of contactor K2 is closed, now coil windings 8 are every mutually seals in
Resistance be R1 resistance, so as to reduce the electric current in coil windings 8, in the presence of load, permanent magnet speed regulation device it is inside and outside
The revolutional slip increase of rotor, so as to realize speed governing；If disconnecting probe of contactor K2, probe of contactor K3 is closed, coil windings 8
In per mutually seal in resistance be R1+R2 resistance, now the electric current in coil windings 8 be lowered again, revolutional slip continues to increase, this
When rotating speed continue to decline on the basis of higher level's speed governing；Similarly, disconnect successively and close contactors at different levels, the concatenation of coil windings 8
Resistance is stepped up, then the rotating speed of power output shaft 13 will gradually reduce；Therefore by reasonably designing resistance values at different levels, both may be used
Realize multistep speed regulation process.
