Description
Technical field
The utility model relates to a kind of permagnetic synchronous motor and uses the bread producing machine of this synchronous machine, refers to the controlled single-phase claw-pole permanent magnet synchronous motor of a kind of slow-speed of revolution self-starting direction especially.
Background technology
In the prior art, bread producing machine includes fuselage, be positioned at the baking box of fuselage, be installed in the loam cake at fuselage top; Described loam cake, baking box, fuselage can be surrounded as the manufacturing chamber of a sealing; Bread barrel is arranged in described manufacturing chamber, and body wall, stirring vane that rabbling mechanism passes bread barrel are positioned at bread barrel and stir; Heating element is positioned at bread barrel outside, described manufacturing chamber; Motor is positioned at outside, described manufacturing chamber, works by the actuator drives rabbling mechanism.
The equal motor employing high-speed electric expreess locomotive of the drive part of existing home-use bread producing machine (rotating speed passes through transmission device generally 1500～2000R/M): the deceleration of belt and belt pulley, stir face requirement rotating speed (100～150R/M) thereby reach bread producing machine.Just there is a problem in this, and Belt Transmission Efficiency is low, is roughly 70%, and the life-span of belt and belt pulley often goes wrong, and cause bread producing machine to lose efficacy, and in the belt rotation process, noise is bigger.The transmission device of existing bread producing machine slows down by belt usually, includes small belt pulley and big belt pulley, because gearratio is bigger, small belt pulley and big belt pulley diameter differ bigger, and the number of teeth of small belt pulley and belt engages is few, belt skids easily, causes operational failure.Existing bread producing machine, the bread producing machine of employing high-speed electric expreess locomotive and belt and belt pulley transmission also exists volume bigger, baroque shortcoming.
In order to solve the problems referred to above that prior art exists, consider to adopt the drive part of Low speed electric motor as bread producing machine.Motor has generally included stator, rotor, end cap.In the claw-pole permanent magnet synchronous motor of existing comparative maturity, the motor shaft actual speed mostly is 750R/M greatly, all is to slow down and reach more slow-revving (as: 5R/M) through transmission mechanisms such as gears.According to pawl utmost point homochronousness Principle of Electric Engine, motor speed is by the number of the lower claw utmost point on the motor stator, the number of rotor permanent magnet and supply frequency decision, under the constant condition of frequency, motor pawl number of poles is many more, the rotor magnetic pole logarithm is many more, and rotating speed is slow more, and claw pole stator and the appearance of rotor magnetic pole logarithm coupling.As: rotating speed is the motor of 750R/M, and the lower claw number of poles is 4 on the stator, and the magnetic pole logarithm of rotor permanent magnet is 4 utmost points.And the rotor magnetic pole is 24 pairs, and under the condition of 50Hz, motor speed is 125R/M.The computing formula of motor speed is n=60*f/P.N is a motor speed, and f is a supply frequency, and P is the rotor magnetic pole logarithm.
The more than just slow-revving theoretical assurance of motor, but on engineering, stator is owing to be single-phase alternating current, and the magnetic field that stator produces not is rotating magnetic field, but single-phase impulsive magnetic field, like this, motor is when starting, it is uncontrollable not only to start direction, even the vibration when starting all is difficult to overcome.Common existing way is made twin coil with motor stator exactly, and the pawl utmost point is as two-layer up and down, and inserts phase modulation electric capacity between the stator twin coil.Because the restriction of prior art middle and slow speed of revolution rotor structure usually produces vibration consumingly during electric motor starting, cause motor normally not start.Because the restriction in bread producing machine structure and space does not allow that this motor solves the vibration problem that starts and start according to existing method.
