1.5-Inch (38mm) High Performance Motors
For applications requiring a motor smaller than our 2.4-inch motors, we offer these 1.5-inch motors. Neodymium magnets give these motors surprising power in a tiny package.
We stock these motors but if they are not quite right for your project, we can design custom brushed or brushless motors.

1 The above specifications are for 24V or 48V. The RPM is proportional to the voltage so running a motor at half its nominal voltage will result in half the no-load RPM shown above. 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. Please note that the above torque figures are the theoretical peak torques when stalled. Operating any high-performance motor while stalled will damage it.
Efficiency
Getting high efficiency from a low-voltage motor is not easy. There are many factors that affect efficiency. We have optimized each of these factors to achieve very high efficiency in these motors.

| Current at PE | 7 Amps | 3.8 Amps |
The RPM is the same in both directions to within about 5%.
Here are our recommendations regarding the selection of a proper reduction ratio.
Warranty
The motors are warranted to be free from manufacturing defects, and fully operational when you receive them. AmpFlow gives no other warranty, either expressed or implied. Warranties are not transferable. In no event shall AmpFlow's liability exceed the buyer's purchase price, nor shall AmpFlow be liable for any indirect or consequential damages.
