When you increase the throttle on your controller, what you are doing is increasing the amount of electrical power drawn from your power supply (i.e. battery) and fed to your motor via the ESC. If you want to slow down the motor, reduce power; If you want to speed up the motor, cr...
Traditional vehicles “coast” when you remove your foot from the accelerator pedal. One-Pedal Driving uses the electric motor to capture energy from the vehicle’s motion to recharge the battery and quickly slow down the car. When you need to stop suddenly in an emergency, you should still ...
At the same time, it blends in the dynamic braking, using the motors to slow the train down as well. A computerized readout displays data from sensors all over the locomotive. It can provide the engineer or mechanics with information that can help diagnose problems. For instance, if the ...
An Inverter Drive (VFD) works by taking AC mains (single or three phase) and first rectifying it into DC, the DC is usually smoothed with Capacitors and often a DC choke before it is connected to a network of Power Transistors to turn it into three phases for the motor. The network of...
Getting rid of the brushes also saves having to replace them every so often when friction wears them down. Here are some photos of a typical brushless DC motor. First, look at the fully assembled motor shown in the top picture. In a normal motor, you'd expect the inner coil to rotate...
PMW has become a commonly used method to do just this. But another option that’s gaining popularity is controlling the speed and direction of a DC motor by using a joystick. How it works: when the joystick is at the center position, the DC motor stops. When the joystick is moved up...
At the same time, it blends in the dynamic braking, using the motors to slow the train down as well. A computerized readout displays data from sensors all over the locomotive. It can provide the engineer or mechanics with information that can help diagnose problems. For instance, if the ...
Also, the charging time will slow down considerably if you're refueling your EV past 80% capacity. Lastly, weather and environmental conditions can impact DC fast charging times. Colder temperatures can increase the amount of time it takes to replenish the charge in your EV's battery. Here ...
Acceleration is much more interesting than speed and more useful if you need to get out of danger behind the wheel: it's how quickly something can speed up or slow down. Measuring acceleration is a bit more tricky than measuring speed because it involves figuring out how speed changes over ...
There are certainly other sizes on both ends of the spectrum from pico up to giant, but these 4 should have you covered 90% of the time; for RC helicopters anyways. The larger the servo, the more torque for a given speed it can produce since it uses a larger and more powerful motor...
