Problems solved by technology

However, the pure amorphous iron core motor has a magnetostrictive effect. When the magnetic induction intensity is relatively large and the frequency is high, the noise will be relatively large during operation. This is unacceptable in new energy vehicles. Traditional The efficiency and power of motors with pure silicon steel cores used as drive motors in new energy vehicles are low, neither of which can best meet the needs of new energy vehicles

Abstract

The invention discloses a motor integrating amorphous alloy and silicon steel as a stator core. The motor comprises a motor shell, stators and rotors are arranged in the motor shell, the stators comprise a first stator and a second stator, the first stator and the second stator are independently arranged, the first stator is made of amorphous alloy, the first stator is connected with an amorphousstator winding, the second stator is made of silicon steel, and the second stator is connected with a silicon steel stator winding; and the outer sides of the first stator and the second stator are fixedly connected with the inner side of the motor shell, the center of the motor shell is connected with a rotating shaft through a bearing, the outer side of the rotating shaft is sleeved with the rotors, the rotors comprise a first rotor and a second rotor, the first rotor and the second rotor correspond to the first stator and the second stator in positions respectively, and air gaps are formedbetween the first rotor and the first stator and between the second rotor and the second stator.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a motor integrating amorphous alloy and silicon steel as a stator core. Background technique [0002] my country has independently developed drive motors that meet the needs of various new energy vehicles, and some of its performance indicators have reached the international advanced level of the same power level, but there is still a certain gap with foreign technologies in terms of peak speed, power density and efficiency. It is still important and necessary to develop and optimize new motors and their drive systems that are more efficient, reliable, and cost-effective. The working efficiency of the motor with pure amorphous iron core is much higher than that of the motor with silicon steel core. The magnetic permeability of the iron-based amorphous alloy material is about 6 times that of silicon steel at power frequency, so the design of the amorphous iron core motor The exc...
