What Electric Company Service At 105 Sunset Drive Saylorsburg Pa
- Work is the result of a force acting over some distance. Work is quantified in joules (Nm) or foot-pounds.
- Torque is a rotating strength produced past a motor'southward crankshaft. The more torque the motor produces, the greater is its power to perform work. Since torque is a vector acting in a direction it is commonly quantified by the units Nm or pound-anxiety.
- Power is how speedily work is accomplished - work in a given amount of time. Power is quantified in watts (J/due south) or horse power.
Note that the driving strength of an electrical motor is torque - non horsepower. The torque is the twisting force that makes the motor running and the torque is active from 0% to 100% operating speed.
The power produced by the motor depends on the speed of the motor and is
- nada at 0% speed, and
- normally at it's height at operating speed
Notation! - the full torque from nothing speed is a major reward for electrical vehicles.

Electrical Motor Power, Velocity and Torque Equations
Torque in Imperial units can be calculated as
Tinlb = Php 63025 / n (i)
where
Tinlb = torque (in lbf)
Php = horsepower delivered by the electric motor (hp)
northward = revolution per minute (rpm)
Alternatively
Tftlb = Php 5252 / n (1b)
where
Tftlb = torque (lbf ft)
- 1 ft lbf = 1.356 Nm
Torque in SI units can exist calculated as
TNm = P W nine.549 / n (2)
where
TNm = torque (Nm)
PW = power (watts)
n = revolution per minute (rpm)
- Torque - Work done and Ability transmitted
Electric Motor - Torque vs. Power and Speed
power (kW)
speed (rpm)
- ane hp = 0.746 kW - power converter
- i lb ft = 1.355 Nm - torque converter
Electrical Motor - Power vs. Torque and Speed
torque (Nm)
speed (rpm)
Electric Motor - Speed vs. Power and Torque
power (kW)
torque (Nm)
Example - Torque from an Electrical Motor
The torque delivered from an electrical motor producing 0.75 kW (750 W) at speed 2000 rpm tin can be calculated equally
T = (750 W) 9.549 / (2000 rpm)
= 3.half dozen (Nm)
Example - Torque from an Electrical Motor
The torque delivered from an electrical motor producing 100 hp at speed 1000 rpm can be calculated as
T = (100 hp) 63025 / (chiliad rpm)
= 6303 (lbf in)
To convert to pound-force human foot - divide the torque by 12.
- Car engine torque
