Which motor is best for a battery-powered application?
One key motor performance parameter to consider in a battery-powered application is efficiency. Maximizing motor efficiency helps minimize the required power capacity and hence the size and cost of the battery solution. For this reason, brushless DC (BLDC) motors are preferred over brushed DC motors but are typically higher in price.
What determines the power requirements of an electric motor?
Power Requirements In any electric motor application, the desired equipment performance dictates the power requirements of the motor. The rated power of the motor is calculated from the combination of speed, torque, and duty cycle of the application that in turn establishes the critical voltage, current, and capacity requirements of the battery.
How does battery voltage affect motor speed?
Batteries also see a decrease in terminal voltage as the output current (load) increases, which also negatively impacts motor speeds at higher torque loads. These factors do not consider the characteristics of the motor winding itself, where output speed decreases as the motor load increases, even with constant battery voltage (see Graph 1, below).
Why do motors reduce battery life more than normal operation?
Motors draw more current when they start (to overcome the inertia of the mass or friction in gears) than during normal operation, therefore they will reduce the battery life more than normal operation.
How much battery does a 50kw motor use?
A 50kW motor running at maximum power will consume 50kWh of battery energy in one hour. A 50kWh battery can also supply a 100kW motor, but it will run out in 30 minutes at constant maximum power. Hence, battery size will give you an idea of the range an EV can travel on a full charge.
Are all batteries created equal?
Not all batteries are created equal, make sure the voltage is at an appropriate level. For example, while a 3V motor will likely run from a 1.5V AA battery but you will get better performance connecting two AA batteries in series to create a 3V supply.
