Abstract
The utility model relates to a fifteen-slot hexadecapole wind turbine, which comprises a motor shaft, a stator and a rotor, wherein the rotor is arranged on the motor shaft, the stator is provided with a fifteen-slot, and the rotor is provided with a hexadecapole. The fifteen-slot hexadecapole wind turbine has simple structure, small volume, beauty and utility, the stators use the fifteen-slot, the stator uses the hexadecapole, the structure of a stator-rotor fractional slot has small starting moment and large power, can start a generator to generate in breeze, and increases the use rate of wind energy. The rotor is a magnetizer which is arranged by two magnetic poles to form a magnetic pole, and has high magnetic density, simple making and low cost.
Description
Technical field
The utility model relates to a kind of three-phase synchronous motor, specifically, relates to a kind of three-phase synchronous permanent-magnet generator.
Background technology
Existing permanent-magnetic wind driven generator is when starting operation, and its resistance of start square mainly comprises: friction, hysteresis torque and cogging torque.Wherein, even bin and can remove disconnected even number rotor cooperation, switch the groove tooth in the time of nearly all polarity cutting magnetic line, detent torque has produced huge reluctance force, because the existence of the above-mentioned moment of resistance, staring torque when causing generator to start is big, often can not start generating under gentle breeze, and utilization ratio of wind energy is low.Simultaneously, because the utmost point groove number of generator is many, the wire insertion technology more complicated, volume is relatively big, and magnetic pole generally all is the magnetic conductor that adopts magnetic shoe to be made, and cost is than higher.In addition, in the rotor installation process, when putting into the motor abdominal cavity, rotor can make the damage of rotor magnet, thereby make the installation fault of generator increase because electric machine rotor directly contacts the rotor of damaging.
The utility model content
Big, the above-mentioned deficiencies such as cost is high, wire insertion technology complexity of staring torque that the utility model exists at existing wind-driven generator, provide a kind of simple in structure, volume is little, staring torque is little, and low, both artistic and practical 15 grooves, ten sextupole wind-driven generators of cost.
The technical solution of the utility model is: a kind of 15 grooves, ten sextupole wind-driven generators, and this generator comprises motor shaft, stator and rotor, and rotor is installed on the motor shaft, and described stator is set to 15 grooves, and rotor is set to ten sextupoles;
Preferably, described rotor is dark utmost point formula rotor or bright utmost point formula rotor;
Preferably, described rotor is installed on the motor shaft by an aluminium dish; The cooperation of described aluminium dish heat is installed on the motor shaft, and the two ends of rotor are embedded in the aluminium dish;
Preferably, described rotor is the magnetic conductor that is formed a magnetic pole by two identical pole arrangement of magnet steel.
The beneficial effects of the utility model are: the utility model is simple in structure, volume is little, both artistic and practical, and stator adopts 15 grooves, and rotor adopts ten sextupoles, the structure of this rotor fractional-slot, staring torque is little, and power is big, can improve utilization ratio of wind energy in starter-generator generating under the gentle breeze.And rotor is the magnetic conductor that is formed a magnetic pole by two identical pole arrangement of magnet steel, and the magnetic density height is made simply, and cost is low.Rotor of the present utility model is connected with electrode axis by the aluminium dish, and rotor is embedded in the aluminium dish, compact overall structure, and the rotor of can not damaging when rotor is put into the motor abdominal cavity, aluminium dish heat cooperates and is installed on the electrode axis, has strengthened transverse strength.
