Easy profits were made by buying inputs (often from oneself) at fixed state prices, diverting them to cooperative production, and then selling at much higher prices.
It also includes, Hall element inputs, a sequencer for commutation control, fixed off time pulse width modulation (PWM) current control and locked rotor protection.
它还包括霍尔元件输入、整流控制定序器、固定停机时间脉冲宽度调制(PWM)电流控制以及锁定转子保护。

Law of diminishing returns — the relationship between inputs and outputs when some inputs are increased and others are fixed, eventually leading to the decreased productivity of variable inputs.
