How large of a flywheel can my motor spin? | Physics ForumsMar 02, 2017· I'm looking to determine how large (diameter / weight) of a flywheel a particular AC motor can spin from a stop to full RPM given the torque / HP of the motor. For instance, if I have a 1/3 HP 115v AC motor, which operates at 1725 RPM, I know the torque is ~ lbs/ft.
"EXPERIENCE WITH SYNCHRONOUS AND CimentecThe torque speed characteristic of a 4100 hp 900rpm synchronous motor is shown in Figure 4. The curves are plotted for three values of stator terminal voltage. Differentiating Characteristics The stator winding of a synchronous motor is no different than the stator windings of an induction motor.

Induction motor WikipediaSince rotation at synchronous speed would result in no induced rotor current, an induction motor always operates slightly slower than synchronous speed. The difference, or "slip," between actual and synchronous speed varies from about % to % for standard Design B torque curve induction motors.

Baldor Basics: Understanding Torque Power TransmissionT = HP × 63,025 T = Torque in lb. in. S S = Speed in RPM OR T = HP × 1,000,000 T = Torque in in. ounces S S = Speed in RPM In order to save time, graphs and tables are frequently used to show values of torque, speed and horsepower. The previous discussion applies to calculations for all singlespeed loads where the required torque and speed for a
Horsepower Torque Dec 03, 2008· From there the torque would drop as a curve keeping the formula accurate. Below 1200 he has less than HP. A HP motor with a base speed of 600 RPM Would show a linear line from 0 to 600 RPM and from 0 to 66 ft/lbs of torque. Fanucs alpha ip motors can have base speeds as low as 500 RPM The torque chart is your dyno sheet for your machine.
Motor Torque/Speed Curve Tutorial:::Understanding ...In order to effectively design with motors, it is necessary to understand their characteristic curves. For every motor, there is a specific Torque/Speed curve and Power curve. The graph above shows a torque/speed curve of a typical motor. Note that torque is inversely proportioal to the speed .

Torque and Horsepower A PrimerIn contrast to a torque curve (and the matching pushback into your seat), horsepower rises rapidly with rpm, especially when torque values are also climbing. Horsepower will continue to climb, however, until well past the torque peak, and will continue to rise as engine speed climbs, until the torque curve really begins to plummet, faster than ...

Work, Power and Torque marinedieselsIf we assume that Dobbin is moving at 1rpm, then the radius of the bar rotating the mill wheel is 181/2p = . So if dobbin is exerting a force of 180lb, the torque is × 180 = f.. If we know the torque and the RPM we can caculate the power.
Speed Control Motors Variable Speed MotorsBrushless DC motors offer 804000 r/min with a flat torque curve allowing for constant speed with varying loads. Motor Footprint. Brushless DC motor's torque density is higher than AC gear motors, allowing for a more compact design. Using hall effect sensors allows for closed loop control and maximum design flexibility.
