500W Brushless Magnetic Motor for Automotive Steering Systems
$ 30.0
Description
This batch of brushless motor is Audi car steering power above the rotary brushless motor, very good workmanship, double nsk bearings, internal rotor is a strong magnet. Rated power 500W, in the use of high-power state should pay attention to the motor's heat dissipation, the maximum torque of 3.5N.m, weight 1.8kg. this motor sensor is a high-end resolver sensor, accurate perception of the motor running angle, to accurately control the motor to use a special controller, connect to the ordinary controller do not care about it. Motor is a three-phase brushless 9N6P, stator coil diameter 1.8mm (national standard 2.5 flat), single-wire winding, thick 1.5mm copper rows of copper welding, each phase of the 3 groups of coils (I do not know whether in series or parallel), each stator pole divided into 3 small magnetic poles; 3-segmented rare-earth magnets outsourced stainless steel riot-proof rotor, the angle of each section is somewhat offset, the rotor into a diagonal strip for each pole, a total of 18 pieces of rare-earth magnets. This motor has a wide range of uses, and current buyers have used it in the following applications: lathe power, milling machine power, table drill power, table saw power, marine propulsion, lawn mowers, water pumps, and more. In turn, it can also be used to generate electricity with high efficiency. Speed 1650, generator side by 3-phase rectification and filtering and then connected to the false load, the output DC5.6v. DC current about 1A more than Speed 2300, generator side condition same as above, output DC8.3v, DC current about 6A. RPM 3340, generator-side conditions are the same as above output DC11.8v, DC current is about 9A. Due to the reason of non-inductive start, with ordinary electric car controller starting force is small, do not recommend making electric cars, change the bicycle (if used to make children's toy cars or go-karts is possible, but need to be relatively strong hands-on ability, the best reduction ratio is larger, can solve the problem of starting) Test 12V no-load speed at 2400 rpm for a minute or so, no-load current 1.5A, torque is very large, 24V voltage 4800 rpm for a minute, can be combined with the store 7-24V brushless drive, you can run very well!
good, should have at least included a heatsink for the triac. The potentiometer was very sluggish, had to use nu-trol specialty cleaner. The pcb quality was good, good chips, the power level is very proper and to professional standards at least, quite good indeed. very useful product, very proper industrial grade, non-generic brand. The stand is also extremely solid or I would think overkill, but can't say anything bad. A better design could integrate a digital control to tool.
I had a miscommunication with seller. I rated them one star because the item was not delivered on time and I was charged already. They took an action and my package was delivered yesterday. They checked with me if I received it. I am changing my review to positive for making up for their shortcomings. Thank you so much.
cannot wait any longer need it right now
