2.4-Inch High Performance Motors
Compact and light-weight, these motors are available in two versions; the Neodymium-magnet, four-brush version for uncompromised performance, and a lower-cost, ferrite-magnet two-brush version designed for high-volume OEM use.
See the Standard Motors page for more options. We stock these motors, but with a minimum order of 25 units, we can design custom brushed or brushless motors.

1 The above specifications are for 12V or 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. 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 | 10 Amps | 14 Amps | 7 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.
