Hi guys, how would one measure the lifting force that an electric out runner motor could put out. assuming one knows the rated power of the motor, how does one convert this into lifting force?
Thanks, Ben.
Thanks, Ben.
Topher925 said:Electric motors don't output lifting force. Only mechanical torque at a rotational speed.
One interesting feature is that the magnetic impulse moves around the motor much faster than the motor rotates, like a built in gearing ratio, allowing higher torque at lower rpm, good for direct drive propellers, but these also turn out to be efficient motors for use in geared applications like a helicopter.russ_watters said:Heh - I assumed an "outrunner" was a winch or something. So I guess we need to know that...
The lifting power of an out runner motor is typically measured by attaching the motor to a load cell, which measures the force exerted by the motor as it rotates. The motor can then be powered on and the force measured at different speeds to determine the lifting power.
Lifting power is typically measured in units of force, such as pounds or newtons. This can be converted to other units of force, such as kilograms, as needed.
The weight of the motor can affect its lifting power, as a heavier motor may require more force to lift. However, the design and efficiency of the motor can also play a significant role in its lifting power, so weight alone is not always the determining factor.
Yes, there are several other factors that can affect the lifting power of an out runner motor. These include the type and pitch of the propeller used, the voltage and current supplied to the motor, and the design and quality of the motor itself.
There are several ways to potentially improve the lifting power of an out runner motor. These include using a more efficient motor design, increasing the voltage and current supplied to the motor, and using a higher quality propeller with a suitable pitch for the motor. Additionally, reducing the weight of the motor and its components can also potentially improve lifting power.
