Electric Motor Power
Watts --Heat---- Brakes---- Batteries
The power rating of an electric motor is determined by its operating voltage (volts) and on its current handling capacity (amps) at that operating voltage. The unit of measure is the ‘watt’
Usually an electric motor can handle significantly more power (watts) for a short period of time versus operating continuously.
The amount of power a motor can handle for a short period of time (seconds or minutes) is called ‘peak’ power and the amount of power the motor can handle continuously (hours – days) is called ‘continuous’ power.
The continuous power rating is the rating most useful for electric scooter/bike applications.
The higher the wattage of the motor the higher the voltage or current has to be.
The device that must supply the motor with all the voltage and current it needs (watts) is the battery.
A motor powered by a battery has a capacity limited to the power capacity (voltage x current output per hour ‘ah’) of the battery.
An electric motor is an electro-mechanical device that by design is limited to the amount of current (amps) it can draw (internal resistance). The amount of voltage it can handle can be exceeded, leading to component breakdown and the destruction of the motor.
The input power of a motor is simply the amount of wattage it takes to operate.
The output power of a motor is the amount of wattage the motor offers towards doing work.
The ratio of input power to output power if called the efficiency of the motor. One obviously hopes to get as much power out of a motor as ones put into a motor, but there are no 100% efficient motors. The higher the efficiency the better.
The power lost between input power and output power turns up as heat. Heat is an enemy to all motors and can lead to breakdown if not kept within safety limits.
If a motor can be cooled effectively its power rating can be pushed above normal operating limits.
