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。

Shannon would also contribute to the further development of pulse-code modulation (along with Bell alumni Bernard M Oliver and John R Pierce) at around the same time, using technology that eliminated some of the issues (such as complex circuitry) from the earlier, but conceptually similar, implementation from Briton Alec Reeves in 1938.
