# Motor rpm calculation formula

• The formulas and calculations which appear below should be used for estimating purposes only. It is the responsibility of the customer to specify the required motor The formula states that the system WK2 equivalent is equal to the sum of WK2parts at the prime mover's RPM, or in this case: Red.
ACCELERATION TORQUE CALCULATION: When a machine must be accelerated to a given speed in a certain amount of time, the drive system HP may have to supply additional torque during acceleration to compensate for the load inertia.

The centrifugal force is a ficticious force that only exists in the rotating reference frame, but it can be very useful to help understand some systems (e.g. cornering in a car, or the forces on a rotating DVD).

If I know the torque and rpm that the shaft need to operate at, can I calculate the diameter of the shaft? A motor operating at 60 rpm applying 1,000 Nm of force on a shaft that has a modulus of rigidity of 50 GPa and is 10 cm in length.
• Squirrel cage induction motors are widely used in electric motor drives due to their satisfactory mechanical characteristics (torque, current When starting an induction motor, a large current is required for magnetizing its core, which results in a low power factor, rotor power losses and a...
• Red Plot: The red line shows the power output of the hub motor. The power output is zero at 0 rpm, rises up to a maximum, and then falls back down to zero once the wheel is spinning at its normal unloaded speed. If the motor current is not limited by the controller in any way, then the peak power happens at between 40-50% of the motor's ...
• Sep 09, 2001 · Output RPM = ((Pulses Recieved in 1 sec * 60) / PPR) / Gear Ratio As for Accel and Decel you can store the result of your calculation and every time you update, check weather the new RPM is greater / less then the last value.

(25.57 %, 13.24 A, 28.49 Hz, 857 RPM). The Power will be P = 1.732 *228*13.24*.85 = 4.444 KW which is 40 % of 11 KW instead of 25.57 % (34.88 %, 13.20 A, 39.25 Hz, 1160.0 RPM). P= 1.732*314*13.20*0.85 = 6.10 KW which is 55.47 % of 11 KW instead of 34.88 %.

your calculator: Pitch multiplied by RPM, divided by 1056, divided by Gear Ratio, = MPH e.g.. using the figures supplied above: 19 x 6000 / 1056 / 2 = 53.97 MPH. Theoretical Speed. To convert MPH to Knots, divide by 1.152. e.g. 53.97 / 1.152 = 46.85 Knots Theoretical Speed. FORMULA TO CALCULATE PROPELLER SLIP The true speed of the boat was 45 MPH.
