Description
The present invention relates to a kind of energy-saving motor, comprise stator, rotor, internal fan ring, motor housing.
The kind of motor is a lot, its rotor mostly is an integral body, this motor starting electric current is big, power consumption is many, the commentaries on classics distance is little, temperature height when being with load, motor temperature is higher during Fraquent start, influence the operation of grid power, the three phase mains of this motor one phase time that breaks is not as adding disposal, motor burns out immediately, simultaneously.It is many to make the consumption of this motor silicon steel sheet.
Task of the present invention is to provide in order to overcome above-mentioned the deficiencies in the prior art part that a kind of little power consumption, temperature are low, the output energy is big, the stall safety time is long, change apart from big, starting current is little, the Fraquent start motor temperature is low, motor disconnected one is on good terms and is turned round as usual, disconnected two phase times connect zero line, and single phase poaer supply still can move as usual; The high-efficiency energy-saving motor that silicon steel sheet consumption is few.
Finish the technical scheme of above-mentioned task:
According to the motor inductance magnetic line of force, the action of a magnetic field power, electromagnetic induction magnetic field integration principle, the integral rotor of motor is made up of n section rotor inline, n 〉=2, preferably n=2-10; Be separated by with a growth trend ring between every adjacent two-stage rotor, be with in the growth trend ring and the close-fitting aluminium end ring of its internal diameter; Cover and the close-fitting circular division board of its internal diameter in the aluminium end ring.
There is the evenly equidistant hole of arranging of a circle axis hole periphery of forming the silicon steel sheet of each section rotor; This hole is prismatic hole or olive hole, the rib point prismatic hole of axis hole dorsad preferably, and the tip in prismatic hole and silicon steel sheet edge are groove.
Be enclosed within the width of thickness=growth trend ring of the thickness=aluminium end ring of the circular division board in the growth trend ring; The interior circular diameter that institute's perforate surrounds around the diameter of division board＜composition rotor silicon steel sheet.
In the growth trend periphery, towards the ring heart, evenly equidistantly have a circle circular hole, institute opened between two adjacent slots around each circular hole was in and forms the rotor silicon steel sheet; The number of this circular hole equals to form the number of being slotted around the silicon steel sheet of rotor, and growth trend ring and circular division board are that ferrous metal is made.
The present invention's beneficial effect compared with prior art is: 1. little power consumption, and 10-20% on average economizes on electricity; 2. it is big 64.29% times to export energy, and starting current is little by 64.67%, starts repeatedly 60 times/minute, and starting current is lower; 3. change apart from big by 50%; 4. the disconnected phase of motor, safe operation as usual, disconnected two-phase connects zero line, and single phase poaer supply still can continue operation; 5. the stall safety time is long, improves more than three times than general motor; 6. be used in " on the motor electricity generation system ", under same power source condition, comparable former " system " increases generating output variable 20%; 7. save rotor silicon steel material about 20%.
Performance test is as follows:
Project test value design load standard and tolerance
Locked-rotor torque/full-load torque is 2.7 2.5 2.2-1.9 doubly
Breakdown torque/full-load torque is 3.1 2.86 2.3-2.1 doubly
Pull up torque/full-load torque is 2.3 1.5-1.3 doubly
Fully loaded temperature rise: stator winding K 67 80
(electric-resistivity method) stator core K 35
Full-load slip % 5.1 4.9
Powerful every starting test frequently (the old and new's machine each hour is all 2.2KW)
Type voltage starting current load time/minute room temperature machine temperature power consumption degree economize on electricity
