First, 1 horsepower is defined as 550 foot-pounds per second (readHow Horsepower Worksto find out how they got that number). The units of torque are pound-feet. So to get from torque to horsepower, you need the "per second" term. You get that by multiplying the torque by the e...
Unlike traditional automatic transmissions - which use torque converters or fluid coupling to transmit power from the engine to the gearbox - semi-automatic gearboxes often use a clutch mechanism like that found in manual transmissions. Instead of cables and pipes running from the transmission to ...

各国使用的交流供电电源,无论是用于家庭还是用于工厂,其电压和频率均为400V/50Hz 或200V/60Hz(50Hz),等等。通常,把电压和频率固定不变的交流电变换为电压或频率可 变的交流电的装置称作“变频器”。为了产生可变的电压和频率,该设备首先要把电源的交流 电变换为直流电(DC)。把直 ...
