MORE POWER
an electric motor can be build with over 2000 rpm,by increasing the supply frequency.
You would use a worm drive meshed with a gear that has 130 teeth.
The two main factors are the frequency and the number of poles of the motor. A formula for RPM is HZ x 60 x 2/ number of poles the motor has.
The most likely reason for an electric motor to slow down after reaching its operating RPM is due to the increase in mechanical load or friction it experiences. This can be caused by a variety of factors, such as increased resistance in the motor's bearings, increased resistance in the driven load, or inadequate power supply to the motor. To maintain the desired RPM, it may require adjustments to the load or power supply.
Yes, however, the RPM will increase by 20%, if the motor is connected to a shaft or driving something that can not handle the torque, then you might run to heating issues or performance issues.
YOU WILL HAVE TO INCREASE THE IDLE RPM.
Yea, but what if you are building the motor yourself and need to know the maximum rpm it will reach.
Materials for producing 2900 rpm motor is less than 1450 rpm one
Current shall increase while you apply 415V for operating it and will decrease the rpm to a much low level.
