Answer:different brushless DC motor technologies are suitable for different applications. Slotted brushless DC motors are suitable for applications such as electric vehicles or home appliances where a higher pole count is required and final size is not an i...
Answer:Brushless motors have three control methods: square wave control, sine wave control, and FOC control. The controller sometimes causes the motor to be unloaded or the current and voltage are adjusted. This requires maintenance according to the specifi...
Answer:The small micromotor has been precision processed to ensure accurate positioning and can be made smaller, lighter and thinner while maintaining the same output torque. Micromotors have many advantages.
Answer:Motors used in automobiles are divided into two categories, namely asynchronous AC motors and permanent magnet synchronous motors. In the past, a few brands of vehicles used asynchronous motors, but now they are mainly synchronous motors. So what are...
Answer:In micromotors, working efficiency is an important reference factor. The efficiency of micromotors is already determined during design and selection. For example, the efficiency of permanent magnet DC motors is higher than that of AC asynchronous mot...
Answer:The role of the position sensor in the micromotor is to measure the position of the rotor magnetic pole, provide commutation information for the circuit switch, convert the position signal of the rotor magnet pole into an electrical signal, and then ...
Answer:As an indispensable and important power provider in people's production and life, motors will generate serious heat during use. However, many times we don't know how to solve it. What's more serious is that we don't know what the ...
Answer:The relationship between the rated current of the motor and the operating current is that the rated current of the motor refers to the current that the motor can operate stably for a long time at the rated voltage. The operating current refers to the...
Answer:The promulgation and implementation of the national standard "Energy Efficiency Limit Values and Energy Efficiency Levels of Small and Medium-sized Three-phase Asynchronous Motors" (GB 18613-2006) was officially implemented on July 1, 2007. It s
Answer:When inspecting the micro gear reduction motor, the gear box of the reduction motor should be opened. If circumstances do not allow it, just opening the observation hole is also acceptable. Wipe the surface of the gear teeth of the reducer clean and ...
