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 ...
Answer:Micro gear reduction motors are widely used in textile machinery, filling machines, powder packaging machines, dosing machines, pharmaceutical machinery, printing machinery, belt conveyors, material handling lines and other industries.
Answer:The motor slot fill rate should not be too high or too low. Generally, the slot fill rate is 75~85%. When the motor is running, the wires loosen in the slot, which can easily damage the insulation. In addition, there are many gaps in the slot, and du...
Answer:Insulation is an important component of motor products. The special cable itself, windings and transformer cores, winding phases, and turns all use different insulation materials. The insulation structures used in motor windings are very different, a...
Answer:The losses of the motor mainly include stator copper loss, stator core loss, rotor core loss, permanent magnet eddy current loss, mechanical loss (bearing friction loss + wind wear loss) and stray loss.
