Wheel Motors

 

 

The AmpFlow Wheel/Gearmotor combination can be configured with your choice of six different wheel sizes and ten different motors.

The high-traction solid rubber wheels are 1.5 inches wide and they range in diameter from 4 inches to 10 inches. The big pneumatic 12.5-inch wheel pictured on the left is 2.75 inches wide.

The solid rubber wheels have a custom hub that is keyed to the wheel and also to the 3/4-inch shaft of the speed reducer. The wheel is assembled with 1/4-inch keys and held in place by two aluminum discs and a spacer. The whole assembly is held together by a 5/16-18 screw that threads directly into the shaft.

The 12.5-inch pneumatic wheel also has a 3/4-inch hub that slips onto the shaft of the speed reducer.

This combination of high power, high traction, and light weight make these wheels ideal for robots and other mobile applications.

* The above specifications are for 24V. The motors can also be used at 12V or 18V. The RPM is proportional to the voltage so running at 12V will result in half the no-load RPM that is shown above for 24V. The lower voltage also reduces the maximum achievable torque by 50%. The motors have also been tested and used at higher voltages resulting in higher RPM, torque, and power. Shorter duty-cycles are recommended for higher voltages to allow the motors time to cool.

The fan-motors have ventilation holes in the front and rear aluminum plates to allow for flow-through cooling. The holes in the front plate are positioned so they are not blocked when mounting the motor to a flat surface. These motors also feature low-profile motor leads for better fit into smaller spaces.

* Theoretical peak power is 11.5 HP. Power at the recommended short-term current limit of 200A is 9.1 HP.
** The current required to reach 3740 in-lbs is far outside the safe operating limits of this motor. This figure is theoretical and should be used for comparative purposes only.
