To increase the torque … that a bit harder. All you can do, electrically (as you can do it mechanically via gears), is to reduce the source impedance to maximise the current that can be delivered for a given stator impedance. Rewind it with more turns of thinner wire.
What gives a motor more torque?
The amount of torque produced is directly proportional to the air flowing through the engine. Large engines pump more air and, therefore, produce more torque.
How can you increase the strength of an electric motor?
Answer: To increase the speed of the motor: Increase the current in the coil. Increase the number of loops on the spinning coil. Increase the strength of the magnet.
How do you increase load torque?
As the speed of the rotor shaft increases the load torque decreases because the output power supplied by the motor is constant. The load torque is increased by increasing the load current and the load current is increased by increasing the mechanical load on the shaft of the motor.
Is it better to have more torque or horsepower?
Torque, simply, is the ability of a vehicle to perform work — specifically, the twisting force applied by the crankshaft. Horsepower is how rapidly the vehicle can perform that work. … Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms.
Why do electric cars produce more torque?
But while they’re fast, it takes them a little longer to hit their maximum torque than an electric vehicle (EV). That’s because the electric motor inside of an EV generates torque in a way that produces the necessary force to get the car moving quicker than its conventional counterpart.
Do electric motors have more torque?
That’s possible because at lower speeds, electric motors deliver more torque than gas engines. “Torque is what you need to get a car going,” says Grace, and with more of it, electrics out-accelerate comparable gas engines.
Do electric motors have constant torque?
So electric motor torque is not constant. There is a region of operation in conjunction with the controller and for certain load conditions which will give the appearance of constant torque.
What makes a motor spin faster?
ANSWER: In order to make the motor spin faster or slower you must increase or decrease the strength of the magnetic field. This is done by either changing the amount of current running through the motor or varying the distance of the permanent magnets from the motor.
What are the materials need to create a simple motor?
MATERIALS: For each motor you’ll need one C battery, a small but strong magnet, about three feet of magnet wire (buy it at Radio Shack, online, or any hardware store), two safety pins, a rubber band, sticky putty, and a small piece of sandpaper. Magnet wire has a plastic coating.
What is Fleming’s left hand rule?
Fleming’s left – hand rule states that if we stretch the thumb, middle finger and the index finger of the left hand in such a way that they make an angle of 90 degrees(Perpendicular to each other) and the conductor placed in the magnetic field experiences Magnetic force.
