Increasing core length properly can raise motor efficiency and power factor, but it will reduce locked-rotor torqueratio and breakdown torqueratio.
适当增加铁心长度可以有效提高电机效率和功率因数,但会导致启动转矩倍数和最大转矩倍数减小。

Thrust ratios between driving and driven pulleys at several different speed ratios were plotted with respect to torqueratio and compared with each other.
绘出了不同速比下主、从动带轮间相对于转矩比的推力比线图并作相互比较。
