What makes a DC motor more powerful?
Yes, since the power of your motor is related to the voltage and the current, a higher wattage at the same voltage will result in higher torque. Q2: The voltage itself will only affect the speed, the current needs to be increased in order to increase the torque.
How do I choose a DC motor?
Key criteria for selecting a DC motor includes first finding out what voltage is readily available for the application and what physical size the motor needs to be. Speed and torque can then be considered once these first two parameters are determined. 1. Voltage availability is a critical element in motor selection.
Can you put an electric motor in any car?
Photo: Electric GT Electric GT’s Crate Motor can convert any classic car into an electric vehicle. Battery cells from the secondary market, typically salvaged from low-mileage Teslas, are repackaged to safely mate with various car chassis, from vintage Toyota FJ Cruisers, to Fiat Spyders and Porsches.
How big of an electric motor is needed to power a car?
There is a direct conversion between horsepower and watts: 745.7 watts is 1 horsepower. Car motors for modern vehicles range from about 50 horsepower to 500 horsepower or more. An average medium size family car might have a 150 HP motor. To duplicate that with an electric motor you would need 111,855 watts of power.
How can I convert my car to electric?
Basically, electric conversion involves removing the entire internal combustion engine from a vehicle, installing an electric motor in its place, and also adding a large bank of batteries. A conversion will cost you about $6000 in parts, and about $1000-$3000 for batteries and installation.
How do you calculate the power of an electric motor?
By taking the voltage and multiplying it by the associated current, the power can be determined. A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A.
How does a motor start?
When the supply is connected to the stator of a three-phase induction motor, a rotating magnetic field is produced, and the rotor starts rotating and the induction motor starts. At the time of starting, the motor slip is unity, and the starting current is very large.
What determines motor RPM?
Poles and Speed The number of poles, combined with the ac line frequency (Hertz, Hz), are all that determine the no-load revolutions per minute (rpm) of the motor. So, all four-pole motors will run at the same speed under no-load conditions, all six-pole motors will run at the same speed, and so on.
Does voltage affect motor speed?
Back to the original question: how does voltage affect speed? From the analysis above, we can see that when the load (torque) on the motor is constant, speed is directly proportional to supply voltage. And, when the voltage remains constant, an increase in the load (torque) on the motor results in a decrease in speed.
