The unit hertz (Hz) is a measure of frequency, with 1 hertz indicating that whatever you're measuring occurs once per second; for example, if your computer screen refreshes itself 40 times per second, the refresh rate would be 40 hertz. Horsepower (HP) is a unit of power, the amount o...
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article onhow to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric ...
Regardless of motor type, the described losses cannot be completely designed out. However, understanding motor efficiency losses matter because less efficient units lead to higher operating costs over the life of the motor. Electric motor output power As described above, electrical motors transform elec...
Method for determining torque of an electric motor on a vehicle, a torque being generated by an electric motor rotor and being transmitted from a drivetrain to at least one drive wheel, including: measuring the rotor rotation angle, determining the torque generated by the rotor, the at least ...
circuit. Current, measured in amps, represents how fast the energy moves through a circuit. For example, you might use horsepower and voltage to find the current in a motor. In order to calculate the current from the horsepower and voltage, you must also know the efficiency of the circuit....

直流电机的工作原理How does an Electric Motor work(DC Motor) 00:01 当你环顾四周, 00:02 你会看到很多带电机的设备, 00:05 例如儿童玩具,台扇, 00:09 电动牙刷,吹风机和电动割刀。 00:14 电动机如何工作的呢? 00:16 只要打开开关,它就开始旋转。
How does electromagnetism make a motor move? The basic idea of an electric motor is really simple: you putelectricityinto it at one end and anaxle(metal rod) rotates at the other end giving you the power to drive a machine of some kind. How does this work in practice? Exactly how do...
If you're familiar with the workings of a basic DC electric motor, you'll notice that mechanical inverters like this also have much in common with commutators. Those are the segmented switching devices that allow a simple DC electric motor to keep on spinning in the same direction by ...
