These ATR wheels are 6 inches in diameter. This item also includes a custom machined shaft with a welded hub that matches the bolt pattern of the wheel. The shaft is 1/2" in diameter and has a 6mm bore to accept a motor D shaft. A lock collar is provided to set screw the shaft to the motor shaft. A sealed ball bearing is provided to support the shaft. The ball bearing mounts into our 2nd generation 32mm ATR frames as well as our custom length ATR sides and our single motor mounts.
These wheels work great with our gear motors. The 6mm bore shafts work with the IG32 and IG32P motors. The smaller IG32 motors will struggle a little, our IG32P medium speed motors work great. With a 8mm bore our IG42 gear motors largest gear motors they will climb virtually anything. To calculate the speed of the robot just take the output RPM * wheel diameter (in inches) * 3.14 / 12 = feet per minute.
The shaft is bored with a 6mm hole for mounting onto the IG32 gear motors.
Inflate tires before use! Underinflated tires can spin on the rim rupturing the tube inside.
These shafts are made to order and may require a 1-2 business days before shipment.
The DXe is the affordable way to equip your sport plane or trainer with the speed, and reliability of DSMX control. Of course it works great for robots too!
This robot uses custom length sides and 13 inch tires with IG52 136 RPM motors. We have included everything to make it ready to run including batteries, chargers, and a controller.
