Speed BLDC motor - induction motor problems
Speed BLDC motor - induction motor problems:
From the electrical point of view of BLDC motor windings burning the cause of the malfunction, and the corresponding treatment.
First, missing running
1 Symptom BLDC motor can not start, even if the load can play a start, slowly increase speed, a hum; BLDC motor smoke fever, accompanied by burning smell.
2 Remove the BLDC motor cover test results can be seen winding end 1 / 3 or 2 / 3 of the pole windings or coke or become dark brown.
3. Failure causes and treatment
(1) motor power supply circuit fuse or a bad circuit by mechanical damage, resulting in a phase fuse blown.
(2) three-phase motor power supply circuit fuse different sizes, small capacity of the fuse. Should be based on the size of motor power, replace the same size fuse.
(3) motor power supply circuit in the switch (isolating switch, plastic lid switch, etc.) and contacts of the contact is bad (burn or loose). Repair and adjust the dynamic and static contact, so that good contact.
(4) lines of a relative phase. Found at the break, and securely connected.
(5) the connection between the motor windings Weld, leading to poor contact. Carefully check the motor windings and weld cable.
Second, the overload
1 speed BLDC motor current exceeds the rating of the motor symptoms; motor temperature exceeds the rated temperature rise.
2 test results BLDC motor winding all three groups burned; bearing frame without grease or sand damage; stator and rotor core with friction, commonly known as sweep chamber.
3. Failure causes and treatment
(1) heavy load, to consider the appropriate load shedding or replacement capacity suitable motor.
(2) The supply voltage is too high or too low, the need to install three-phase power regulator compensation cabinet.
(3) BLDC motor of serious long-term erosion of damp or corrosive gases, insulation resistance. Should be based on specific circumstances, for a major overhaul or replacement of the same capacity, closed with the specifications of the motor.
(4) bearing in oil, dry or rotor mechanical misalignment, leading to sweep rotor chamber, the motor current exceeds the rating. Should first carefully check the bearing wear, and if failed to be replaced with new shaft
Cheng; Second, cleaning bearings and into the amount of grease. Then check the motor cover, cover the center hole if the rotor due to wear and tear resulting in a different heart, should cover the treatment or replacement.
(5) institutional failure of transmission parts, resulting in motor overload and burnout BLDC motor windings. Check the mechanical part of the existing failure to take measures to deal with resolve to make it flexible rotation.

Technological progress to promote the development of BLDC motor
The 21st century, to meet the co-existence with the global environment, combined with the network, in line with the requirements of micro-motor robot will be rapid development, and build "a new era of micro-motor." Coexistence with the global environment, motor energy efficient, higher power saving materials, quiet and comfortable, harmless and pollution-free. Combined with the network, motor miniaturization, sheet, high-speed, lightweight, high-precision and high performance. Meet the robot motors, requiring higher power, low inertia, low speed high torque, intelligence, etc., in order to meet the above requirements, foreign micro motor manufacturing company attaches great importance to BLDC motor and drive control technology research and development. Motor to optimize the design, selecting parameters to reduce the torque ripple and noise, the expansion speed range; multi-pole concentrated winding to reduce the degree of winding end ministers, pieces hinged armature type or improve punching bad full rate, high efficiency performance drive control techniques, high-performance permanent magnetic materials used to make BLDC motor with high efficiency, higher power saving materials, high reliability and high performance, small size and light weight advantages.

buy a bike conversion kit
Years ago, numerous allergic rhinitis can not cure the annoyance, the doctor's advice, the desire to exercise more. Persevering, one week on the five-day classes, morning 8 am to 6 are spent in the company, will be in the garden at night on the road with yellow light running, it is less than the effect. An impulse, to a nearby vehicle dealers to buy a bike conversion kit. The weather is good, step bike conversion kit to work, the idea is to exercise or two.
Saying to buy bike conversion kit, the dealership owner to compare the pros and cons of many bike conversion kit, and later recommended a cost to high, did not care how, they bought with satisfaction, but also feel that the boss man very kind, I thought the future if you want to get a new one, will come back to buy his house.
Since then, the beginning step on bike conversion kit every day to work. Step was tired in the end to exercise, compared to crowded bus in the end still let me a bit more. Sometimes the weather is good, looking at his mouth, roadside flowers and dew, a little unknown faint smell of flowers, the owner of my heart feel good dealers, introduced this bike conversion kit did not give me trouble.
This morning, as usual, went downstairs to his foot bike conversion kit to work. Stamped just a few steps, I feel very wrong, Made in the car after the tire completely without any gas. That depressed ah, causing me a hot day wearing a bike conversion kit gloves. Thought it was only the children downstairs for the prank. Night coming back from dinner, to push the bike conversion kit to a nearby repair point to inflation. Repair master glances bike conversion kit, asking, girl, you where this bike conversion kit to buy?
