Electric cars are pushed by giant electric motors often rated between 3.5 and 28 horsepower. For these accustomed to gasoline engines, this will not appear like much power, however the ranking methods used for gas engines and electric motors are so completely different that the numbering system is sort of meaningless. Fuel engines are rated at their peak hp, electric motors are rated at their continuous hp. The peak hp of an electric motor is normally 8 to 10 times its steady score.

"The three things I look for when changing a motor are cost, the time that it runs and its effectivity. We search for replacements that give us a payback below two years. I will solely restore special motors. Otherwise, we at all times go together with NEMA Premium as a result of they're extra efficient, you have less to worry about and we see a lower in downtime."

Axial flux magnetic machines can produce the next torque than a standard motor of the same size. The reason being that magnetic flux in a traditional radial motor scales with the square of the diameter, эл двигатель асинхронный кг 2412 6 паспорт however flux in an axial machine scales with between the second and third power. So the larger the motor, the bigger the benefit of an axial design.

Benefits of DC motors:
1. It is straightforward to regulate their speed in a variety; their torque-velocity characteristic has, traditionally, been simpler to tailor than that of all AC motor classes. That is why most traction and servo motors have been DC machines. For instance, motors for driving rail vehicles had been, till just lately, solely DC machines.
2. Their lowered general dimensions permit a substantial area saving which let the manufacturer of the machines or of plants to not be conditioned by the exaggerated dimensions of circular motors.
