提出了双转子叶片马达,一个壳体内有内、外两个马达,可通过不同的连接方式输出四种不同的转矩.分析了马达四种工作状态时的瞬时转矩及转矩脉动,当马达差动连接时转矩脉动最小,当两个马达共同工作时转矩脉动最大.研究了不同叶片个数时马达的瞬时转矩,讨论了叶片个数与转矩脉动之间的关系,结果表明:当叶片数为4的奇数倍时转矩脉动的理论值为零;当叶片数为2的奇数倍时会产生一定的转矩脉动;当叶片数为4的偶数倍时会产生较大的转矩脉动.
A double-rotor vane motor is proposed, and there are two motors inside and one inside the housing, which can output four different torques through different connection modes. The instantaneous torque and torque ripple of the four working states are analyzed. The torque ripple is the minimum when the motor differential connection, and the torque ripple is the maximum when the two motors work together.The instantaneous torque of the motor with different number of blades is studied, and the relationship between the number of blades and the torque ripple is discussed. The result It is shown that the theoretical value of torque ripple is zero when the number of blades is an odd multiple of four, a certain torque ripple is generated when the number of blades is an odd multiple of 2, and a large torque ripple is generated when the number of blades is an even multiple of 4 Of the torque ripple.
