View Full Version : Vector Brushless Motor Problems
20-07-2006, 08:36 AM
We have a New 2 star vector brushless motor which has just broke down, after just 2 months, and precious little running.
The rotor has come loose on the shaft.
This is the third motor that I know of that has failed with a rotor type problem.
I only know of three users of this system making it an impressive 100% failure rate of the maintenance free brushless system from LRP.
Does anyone know of any other similar failures?
Are we doing something wrong? or is there a manufacture / design fault?
We run this in our B4 geared on a 21 pinion 81 spurr

Ive seen that before. Its the magnet coming loose right ? clearly a manufacturing fault, send it back to the shop you bought it, or contact LRP direct about it.

Its already on its way back to Helger. But how common is this fault

Ask helger, not that they will tell you of course. I have only seen it once, on the Nosram version. Still, I guess it is something they have seen before.

Erm, sounds like the one I sent back to the shop. LRP 1 Star Brushless. Screws and end bell came loose at the pinion end, you couldnt tighten them up. Sent back to shop and replaced within 2 weeks, but if its the same problem, there seems to be a trend :/

I have one of the very first Vector (3-Star) and if runs without any problem so far.

I dont know if your at bury this wkend, but I've a couple of 1 star and a 3 star ready if you'd like to borrow?

I have a 3* system for my B4 and a 4* system for the ZX5. both have been trouble-free all season so far. I'm very pleased with them.
BUT .... I've noticed some of the motors come with REALLY crappy bearings. :mad: The vibrations generated by these could be the cause of the magnets on the rotor coming lose. My advice would be to check the ball bearings before running it and replacing them if needed.
The only other problems I've seen with the LRP/Nosram BL systems seem to be that some ESC's have a will of their own, demonstrating itself in resetting, engaging the overheat security for no apparent reason, ...
