JOUAV CW-15 Brushless Motor | 124x22mm 1850W | OE JOU-M12422

Short version. A 124 by 22 mm outrunner for one of the four lift positions on a JOUAV CW-15. 1850 W, three phase, ring terminals, six hole prop mount. Motor only.

The aircraft. A fixed wing with four lift rotors hanging off the booms: it takes off like a quadcopter, transitions to wing-borne flight, and cruises on a pusher at the tail. That layout is why the lift motors only work hard for two minutes at each end of the flight.

The number. JOU-M12422 is ours. JOUAV sells the CW series as a complete system with factory service, and does not publish lift motor part numbers to the open market. There is no public cross reference to copy, so the fit has to be checked by measurement.

Why the lift motors are the stressed ones. In the cruise the wing carries the weight and the pusher does the work. In the transition the lift cans are still spinning while the wing starts to fly, and that is where a tired motor or a tired battery makes itself known. A machine that drops a wing on transition is a machine that had a weak corner nobody measured.

Fitting. Battery out. Four base screws out, lift the bell straight, do not lever against the arm. Check the rotation direction before you power up: a lift motor that spins the wrong way turns over on the first take-off attempt and the flight controller cuts it.

Hand check. Turn the bell by hand before and after every rough landing. A click or a rough patch is a bearing. Grit from a grass strip gets past a seal in one season of work, and a seized bearing in a lift motor ends the flight, not the day.

Cleaning. Dry air and a brush, face down to drain. No hose, no pressure washer, no spinning it with compressed air. The bell is open by design and everything you put in it stays there.

Diagnosis. Unequal resistance across the three leads is a winding fault. A motor that is hot after a hover while the other three are cool is either the motor or the ESC, and swapping it to another boom tells you which.

What is not on this page. KV, thrust per motor, stator size, wire gauge and weight are not published for the CW-15 lift can. If you need those figures for a build, ask and we will measure a sample rather than quote a number off a similar motor.

In the box. One motor, three ring terminals, no screws, no prop hub. Six months against dead on arrival and winding faults. Samples ship from stock, twenty pieces starts a run at fifteen to thirty days.
