Why do you need an electronic throttle cable?
Eliminating the mechanical element of a throttle cable and substituting it with fast responding electronics, reduces the number of moving parts (and associated wear) and therefore requires minimum adjustment and maintenance. Greater accuracy of data improves the driveability of the vehicle, which in turn provides better response and economy.
How does twisting the throttle work on an electric bike?
Twisting the throttle moves the contact on a variable resistor. The second type of throttle uses a hall effect sensor. In a hall effect throttle there is a stationary sensor + simple circuit in one part of the throttle. In the moving part of the throttle there is a magnet.
Can a direct short cause a throttle problem?
A direct short might allow too much current to flow through the control circuit which could damage the controller. Then you have two problems to debug : ( A better idea would be to put a resistor between the power and signal. You can pick up a pack of 330 ohm resistors for less than a buck at most electronic supply stores.
Is there a way to test a throttle function?
To qualify a throttle function you probe the leads while connected and powered up. I verify 5V (or close to) supply then measure VDC across signal-to-ground while moving the throttle across it’s range. It should swing roughly 1-4VDC. Yes, you can operate without brake inhibit switches for testing purposes.
What does a fly by wire throttle mean?
Fly-by-wire anything (car, motorcycle, plane) is a system where the throttle is not connected to a carb or throttle body by actuating cable. Usually some type of potentiometer at the throttle that is connected, by wire, to an electronic actuator on the other end. Vey handy in manufacturing if you don’t have to thread a cable or set of cables.
What to do if your ebike throttle is not working?
Check that the e-brake lever is not damaged or engaged. If engaged, this will keep the throttle / motor from operating. 2. Check the connection between the motor and the controller. This is a 3 wire square plug and a 5 wire rectangular plug. You may have to clip a few zip ties to access this plug.
Can a throttle controller last for the life of the car?
Under most circumstances, the throttle controller will last for the life of the vehicle. However, like any other mechanical and electrical component, there are some instances when it will fail, wear out or simply break.
What should the voltage be on a throttle?
The throttle connector is the 3 pin connector usually with red, black and green wires. With a multi-meter you can test the pins for voltage: Black to red approx 5V. Black to green should vary from 1-5V with throttle engagement. The throttles are reliable, and rarely cause issues unless damaged. 4.
