Brushless Etek Motor

From my associates at Inertia Labs comes the perfect way to mount your 3" Magmotor. The feet are slotted so you can easily adjust chain or belt tension. Price is per unit, proper application requires a pair. CNC machined from 6061 aluminum, each weighs 10oz.

Note: Magmotor shown in picture only to demonstrate application of mounts. Magmotor is not included.

Also from my associates at Inertia Labs comes the perfect way to mount your EV Warrior. Just like the RCM130 Magmotor mount, the feet are slotted so you can easily adjust chain or belt tension. You only need one of these per motor. CNC machined from 6061 aluminum, each weighs 11.5 oz.

Note: EV Warrior shown in picture only to demonstrate application of mounts, it is not included.

This is the production version of the wheel bearing blocks that won us three trophies with Evil Fish Tank! and HAZARD in 2000 - now available to you. A 6061 aluminum frame supports two 0.500" bore ball bearings and is perfect for cantilevered drive shafts, intermediate shafts in gear boxes or even small spinning weapon support. Four of these can easily handle a 115 lb. robot (add more for heavier robots!)

Weighs 8.2 oz. and mounts through 1/4-20 tapped threads.

Two of these are perfect for floating a spinning weapon or a drive axle. Choose the bearing diameter that matches your shafting.

A 6061 aluminum frame supports a single ball bearing rated for a 1600 lb. dynamic load, 1000 lb. static. The 1/2" bearing mounts with 1/4-20 threads, the others mount with 3/8-16 threads.

RCM220-500:  1/2" bearing, weight 3.2oz   $19.75

RCM220-625:  5/8" bearing, weight 7.6oz   $23.00

RCM220-750:  3/4" bearing, weight 7.4oz   $23.00

Two of these are perfect for floating a spinning weapon or a drive axle. Choose the bearing diameter that matches your shafting.

RCM230-625:  5/8" bearing, weight 6.8oz

RCM230-750:  3/4" bearing, weight 6.5oz

A 6061 aluminum frame supports a single ball bearing rated for a 1600 lb. dynamic load, 1000 lb. static. Mounts with 5/16" through holes on a 3.5" center distance. 1.000" distance, base to shaft center.

Tony Buchignani and I have used these 18v Dewalt motors to win a lot of fights at BattleBots and BotBash over the years (Hazard, Evil Fish Tank, War Machine, Wedge of Doom.) We got tired of clunky mounting schemes so Peter Abrahamson (Team Sinister) cooked up a super-cool solution.

This face mount for the plastic gearbox is the hot ticket! It locks the torque clutch in place, constrains the gearbox to keep it from bursting and gives you an easy way to mount the motor. Plus it places the output shaft at the proper height to mate with the RCM200 pillow block. Included is a cleverly designed shim for locking your gearbox into either low or high speed.

These are made for the 18v motor and gearbox used in the 995k product - contact your local Dewalt service center for assistance in ordering.

Weighs 3oz.

A brilliant design from American Performance Robotics - this add-on kit is the trick for stabilizing your 18v Dewalt setup. It takes about 20 minutes to install and adds 3oz of weight but it keeps the motor from breaking the plastic ears off the transmission case.

Pictures of an installed kit are here and here.

Instructions included.

Weighs 3oz.

This is the standard Dewalt 18v drill motor.

DeWalt part number 393111-01.

It is designed to mate with the RCM511 transmission, below. Tony Buchignani has some good design tips on his website.

Weighs 17.1 oz

Say, need help retiming (re-phasing) your 18v DeWalt motor? Check out this quick tutorial.

This is the standard Dewalt 18v transmission.

DeWalt part number 380264-15.

It is designed to mate with the RCM510 motor, above. Tony Buchignani has some good design tips on his website.

• In low gear you get 450 RPM at 400 in-lb of torque
  
• In high gear, 1450 RPM at 124 in-lb.
  Weighs 7.1 oz
  

Another work of art from Peter Abrahamson and the boys at RF Ballard & Son machining, this shaft has been carefully engineered for maximum performance with minimal futzing around. It's made of ETD150, a modified chromoly steel that is not super hard but in fact, quite tough - yielding a 150 KPSI part that can be cut with a hacksaw. No hidden costs here with a cumbersome heat treating step either - we've had the splined end induction hardened for you! Hooked up to a special jig it failed at 1200 in-lb. - 3x the max output torque of the Dewalt transmission giving you a 200% safety margin.

Precision ground to fit a 1/2" bearing (like the RCM200) it is 7" overall in length with a 5.5" usable (1/8" standard) keyway.

The standard X-splined version mates with 18v Dewalt transmissions like the ones we sell. We also sell a double-D version (see picture at left) that mates with the 14v Dewalt transmissions.
