I'm getting ready to test a motor that looks like it is going to have some potential. It's a LOSI 1/8 Xcelorin Brushless Motor. The one I have here is 2100KV. They also make one in 1700KV and in 2400KV. The 2100KV version would be similiar to a Neu 1515 1Y. I'd like to try the 2400KV, but I'll be using this on an 3.5cc sized outboard, and I don't thing the .150 shaft would handle the RPMS of the 2400KV version for very long.
Very nicely made unit. Has an 8mm shaft that is turned down to 5mm at the output. Shaft is a little long and I had to cut it down by about 1/4" to get it to fit my other apps.
Endbells have two sets of mounting screws set at 1"... standard 3mm screws, and a set of 4mm screws. I ended up using the 4mm here to get the wire tabs to line-up correctly.
Motor is a 4-pole, 12-slot design, and it the same diameter as a Neu 1515, so the OSE water jackets for Neu fit fine. You have to take out one set of endbell screws to get them on, but they fit perfectly.
The mass of the motor is about 30grams less than the Neu (309g vs. 340), but after looking it over, I think that's due to the outter can construction, which is thinner on the LOSI. That MAY mean, however, that there is more room inside for magnets/windings???
I'm going to try it first on a 30" P-OPC Tunnel that I'll be racing at the Northwest Tunnel Championships in April in an Open class. I should be testing it on the water in a week or so. I'll report back once I have some data to report.
Here are the specs for the 2100KV version I have here:
