What is Electronic Speed Control (ESC)?
At present, we can observe the electric motors' speed control all over modern society. So, the list of speed control mainly includes an extensive range of machines which ranges from basic electrical appliances used in a household like in the garage, or garden to large industrial plants through pumps, machine tools, conveyor belts, etc. So we can notice how important and necessary this speed control technique is for several electrical machines. We cannot perform longer without an efficient method to control speed. So, the electronic speed control method is used to control the machinery as well as motor rotational speed. Next, we will discuss electronic speed control for motors, drones, vehicles, etc.
How Does a BLDC Motor Rotate Forward and Reverse?
The power supply of the DC brushless motor is connected to the brushless motor through the controller so that the DC brushless motor runs in one direction. Looking at the direction of the motor shaft extension, the motor shaft rotates clockwise is called forward rotation, and counterclockwise rotation is called reverse rotation. The following is explain how to wire a controller to reverse a BLDC motor.
What is the Torque Pulsation of BLDC Motor?
Commutation torque pulsation is caused by the PWM inverter of the inverter and is due to current hysteresis or high-frequency current ripple generated by the inverter. During a phase change, when one phase is off and the other phase is on, the rise and fall rates of the individual phase currents are not equal. Therefore, the torque phase generated by the two currents during phase change adds a fully excited torque value, which will allow a smooth torque generation during the commutation interval.
Brushless DC Motor for Household Appliances Field
The modern kitchen is everywhere electrical equipment, now in the process of using household appliances brushless DC motor is more satisfactory, especially in the process of using kitchen appliances can use the help of household appliances brushless DC motor will seem a little better, in the process of using kitchen appliances is more considerable, but also more useful, such as in the use of mixers, juicers, coffee machines, milk tea machines, electric Knives, egg beaters, rice cookers, food processors, grain grinders, vertical mixers, meat grinders, electric cutting knives, and other appliances can be used when using household appliances brushless DC motor.
Does a Brushless DC Motor Need a Controller?
Nowadays, many automation equipment manufacturers have begun to pay attention to DC brushless motors and use them to replace previous low-efficiency, noisy, and high-power motors, such as AC induction motors, stepper motors, etc. Everyone wants to know whether the brushless DC motor and the brushed DC motor can rotate when they are energized. the answer is negative. Because the brushless DC motor must be equipped with a corresponding controller (driver) to rotate, which is determined by the structure and principle of the brushless DC motor.
