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 wheels have a custom hub that is keyed 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 steel discs and a spacer. The whole assembly is held together by a 5/16-18 screw that threads directly into the shaft.
This combination of high power, high traction, and light weight make these wheels ideal for robots and other mobile applications.
We stock 14 different gearmotors or we can design custom gearmotors:
* The above specifications are for the motor's nominal voltage. The motors can also be used at lower or higher voltages. The RPM is proportional to the voltage, so running at half the nominal voltage will result in half the speed, and twice the voltage will double the speed. The maximum achievable torque is also proportional to the voltage. Shorter duty-cycles are recommended for higher voltages to allow the motors time to cool. Please note that the above torque figures are the theoretical peak torques when stalled. Operating any high-performance motor while stalled will damage it.
On Sale! Fan Cooled Motors
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.
VEX High-Voltage Motor Controller
We recommend using the IFI VEX 48V motor speed controller with our 48-volt motors. Visit this page for more details.
Here are charts showing the no-load speed (in MPH) for each Wheel / Motor combination:
The speeds shown above are for the motor's nominal voltage. If a lower or higher speed is required, the motors can be used at lower or higher voltages. The RPM is proportional to the voltage, so running at half the nominal voltage will result in half the speed, and twice the voltage will double the speed. The maximum achievable torque is also proportional to the voltage. Shorter duty-cycles are recommended for higher voltages to allow the motors time to cool. Ideally, the top speed of the WheelMotor would match the top speed required in an application when any electronic speed controls are set to full throttle.
Here are our recommendations regarding the selection of a proper reduction ratio.
