The strength of the motor (torque) is determined by voltage and the length of the wire in an electromagnet in the stator, the longer the wire (which means more coils in the stator) the stronger the magnetic field. This means more power to turn the rotor.
Why are electric motors more powerful?
Electric vehicles generate much more torque than gas vehicles, which is important because torque is what drives the vehicle forward. Furthermore, an electric car’s motor eliminates the need for a traditional transmission in many modern designs.
How can we make the motors to become more powerful?
Motor can be made more powerful by winding the coil on a soft iron core of by increasing the number of turns of the coil.
Can we increase the RPM of motor?
Yes, but with a small amount above the maximum speed under normal rated conditions. Increasing the speed can be achieved by increasing the supply frequency as the speed and frequency are directly proportional; however, there are two constraints.
Do electric motors produce 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.
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.
How powerful can a motor be?
It is the world’s first 36.5 megawatt (49,000 horsepower) HTS ship propulsion motor. … Its capacity surpassed the Navy’s previous test record, doubling the rating. The HTS motor performs at 120 rpm and produces 2.9 million Newton-meters of torque.
