WebNov 16, 2024 · In layman’s terms, horsepower is defined as: the power needed to move 550 pounds one foot, in one second. This is in relation to how much weight a horse can lift, which in Watt’s time was typically around a quarter of a tonne. Really, all you need to remember is that HP is a measurement of the rate at which power is generated. WebBasic mechanical power measurements. In an electric motor, the mechanical power is defined as the speed times the torque. Mechanical power is typically defined as kilowatts (kW) or horsepower (hp) with one watt equaling one joule per second or one Newton-Meter per second. Horsepower is the work done per unit of time.
