Braking Function in XMC300 ESC |
The brake function in the XMC300 ESC is electronic, and the function and intensity of the braking force depends on the motor used in the car. The brake is applied only after there is a switch from forward movement (throttle position on transmitter) to brake application (braking position on transmitter); it does not matter what from what forward throttle position you start (full throttle or partial throttle). The braking intensity is preset at the manufacturer to be 100 % upon application of the brakes. In the case where the transmitter is in neutral and you move the throttle to the brake position, then the brake will not be activated. Also, if the transmitter is already in a partial braking position and you move the trigger further into the braking range (for more progressive braking), a higher braking force will not be applied. This solution was chosen by the manufacturer for the protection of the ESC.
The brake works on the principle of âśshort circuitingâť the motor. Every motor works as dynamo and this characteristic is used by the XMC300. By slowing down the car, the motor turns into a dynamo. When the dynamo is short circuited, the operating speed gets slower and the car brakes. The higher the throttle position from which you apply the brakes (for example, from full throttle), the more braking effect is applied. Brakes applied during partial throttle will seem weaker than brakes applied from full throttle.
In the case where the transmitter is in neutral and you move the throttle to the brake position, then the brake will not be activated. When the car stays on the start line (with brakes applied) and somebody moves the car backwards, inside the motor the negative tension rises which can damage the controller when the brake is on. From these reasons the manufacturer decided for using this kind of brake system. |
