40 Amp Speed Controller for Brushless Motors

DC motor speed control is one of the most useful features of the motor. By controlling the speed of the motor, you can vary the speed of the motor according to the requirements and can get the required operation. ESC stands for Electronic Speed Controller, it uses the same plug as your standard servo. There are a variety of motor speed controllers available. DC Motor Power-Op-Amp Speed Controller.

It may also provide reversing of the motor and dynamic braking. Miniature electronic speed controls are used in electrically powered radio-controlled models.

Thus, the speed of a DC motor can be controlled in three ways:

By varying the supply voltage, By varies the flux, and by varying the current through field winding and By varying the armature voltage, and by varying the armature resistance.

ESCs are normally rated according to maximum current, for example, 40 amperes(40A). Generally, the higher the rating, the larger and heavier the ESC tends to be which is a factor when calculating mass and balance in airplanes. Many modern ESCs support nickel-metal hydride, lithium-ion polymer and lithium iron phosphate batteries with a range of input and cut-off voltages. The type of battery and number of cells connected is an important consideration when choosing a battery eliminator circuit (BEC), whether built into the controller or as a stand-alone unit. A higher number of cells connected will result in a reduced power rating and therefore a lower number of servos supported by an integrated BEC if it uses a linear voltage regulator. A well designed BEC using a switching regulator should not have a similar limitation.
