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.
The basis for making a drone is a brushless motor. The combination of motor and propeller is necessary to keep the whole drone hovering in the air. For the drone to fly as long as possible, a balance needs to be found between the motor, the propeller and the weight of the entire structure. Like all electric motors, brushless motors contain bearings, coils, magnets, and stator and end caps connected by bearings. The important parameters of a brushless motor are KV value, weight, no-load current, the maximum current that can be carried and maximum voltage.
The wiring principle of the general brushless DC motor is basically similar. Here we take a 24V brushless motor as an example to show you how to connect the motor to the controller and make the motor turn.
To test 24V BLDC motor requires a controller, 24V DC power supply start switch, a push button switch & a toggle switch, including power wires and hall wires, as well as a resistive accelerator pedal. All of these constitute the basic parts to operate a BLDC motor.
As the saying goes, "If you want to do a good job, you must first sharpen your tool." As a mechanical component, the electric screwdriver cannot work normally without the electric batch power supply. The electric batch power supply provides energy and related control functions for the electric screwdriver. drive the rotation of the motor. Due to the different parameters of the electric screwdriver motor, the speed will be different when the electric batch power supply outputs the same power.
As a small household appliance, the working principle of the hair dryer is that the motor drives the rotor to drive the fan blades to rotate, the motor is installed in the casing, and the fan blades are installed on the shaft end of the motor. When the motor rotates, the air is sucked from the air inlet and blown out from the air outlet wind.
The working principle of the car vacuum cleaner: the fan impeller of the car vacuum cleaner is driven by a high-speed DC brushless motor to form a vacuum in the host, which generates a high-speed airflow and sucks garbage from the suction port. The high-speed DC brushless motor is the core component of the vacuum cleaner, and the performance of the motor directly affects the reliability and life of the vacuum cleaner.
The hand-push sweeper has become a major demand in the market. It pays attention to efficiency, low cost, and outstanding cleaning effect. As an environmentally friendly technology product that replaces manpower, it integrates "cleaning, watering, and vacuuming". Time-saving and labor-saving, safe and reliable, what is the service life and efficiency of the hand-push sweeper related to?
In robots, the actuators are divided into two types: motor drive and hydraulic drive. The most common one is a motor drive, and the motors used in robots are mostly DC gear motors. The following is the brushless.com geared brushless motor BLDC-GEAR-P100. As the name implies, is a planetary gearbox with a brushless motor. The DC supply current is DC, so it can be powered by a battery, which is why the DC brushless motor is the most widely used in robots.
The design scheme of the outrunner brushless motor for industrial fans has been more than 10 years old, so why do customers choose the external rotor brushless motor as their standard for more than 10 years?
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.
