BOTVAC D7 CONNECTED - LIDAR MOTOR won't spin. ERROR 3000

Postby yonygg » December 4th, 2018, 11:50 am

Hi,

My D7 LDS Motor stopped spinning and I get an Error 3000 on the Neato app.
The motor has barely any marks on it other than the number "1802".
Any ideas of what can cause this?
If it's a defected motor - where can I get a replacement? I couldn't find any.

Thx
yonygg

It should be the same motor used in the D3 and D5 Botvac. Basically a DVD motor.

Are these things still spun by rubber bands?

On my XV-11, I had fuzz blocking the internal optical counter that is used to determine lidar speed. The rubber band would pull in debris to the internal unit and then allow it to accumulate on the sensor.

Not a rubber band - it is actually an O-ring.

That kind of dirt is pretty unusual unless a long time in use. I don't think it has been reported before, compared to motor and belt wear (it is actually an o-ring made for belts instead of plumbing seals, specialty items). This reminds me of one of my earliest posts about a cover to put over the turret when not in use, to keep out any dust -- and provide decoration (deli containers work well) -- no good with scheduled cleaning... Any kind of clear window on the lidar would require a higher power beam, with all sorts of complications even safety regulations (just in case someone took it out and looked into it).

Belt drives are common because the smallest motors operate at high speed using reduction gears or pulleys, and cannot provide torque at low speeds like much heavier -- and more expensive -- motors. You might find such things in lawn mower bots which can have a larger size without furniture to deal with.

One of the Connected that i bought broken, had massive amounts of dog hair between the lidar motor shaft. Lidar was spinning, but not fast enough.

Simple and cheap fix.

If your motor doesnt spin at all, try to apply voltage to it and then spin it with your hands. If it start to spin on its own when on external voltage, its a motor brush or collector failure, which both can be fixed without buying a new motor.

Currently my xv-11 is hit or miss on getting the laser to turn on. About half the time it doesn't come on, and after letting it sit for a day, it usually comes on the next time. Bad cap?
