No. Here's Why - The Green ...Feb 11, 2015·At its most-efficient, 93%, the MG is pushing only 100 N•m at 2,250 rpm, perfect for cruising. In any case, a multispeed electric vehicle transmission is unnecessary because even 100 N•m is plenty of torque at cruising speed. Of course, this doesn’t mean that electric cars couldn’t have gears, but they aren’t necessary.

Apr 14, 2021·But if we convert torque to newton-meters and speed to radians/sec then k will be equal to 1. This means that we can easily calculate the torque of your motor. Let's convert the speed to rad/sec first. 2750 RPM / 60 * 2 * Pi = 288 rad/sec. 250 W / 288 rad/sec = 0.868 Nm.

D. Motor Torque/Speed Curve Tutorial:::Understanding ...

By substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at = ½, and = ½ repectively.

What Determines the Rotating Speed of a Motor?

A 60 Hz power supply changes polarity 60 times per second, and a two-pole motor will spin at 3,600 rpm when connected to this source. A four-pole motor will only rotate at 1,800 rpm. For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles. Using this equation, a 4-pole motor at 60Hz has a speed of 1,800 rpm, while a 6 ...
