Witryna2 paź 2024 · Vector control drive (VCD): Vector control, also called field-oriented control (FOC), is a VFD control method in which the stator currents of a 3-phase AC Electric motor are identified as two orthogonal components that can be visualized with a vector. One component defines the magnetic flux of the motor, the other the torque. Witryna2 gru 2014 · The actuator is inoperative (undesirable in most applications) for a period of time allowing the motor to cool and the thermal overload to reset. Variables: Duty Cycle = D, On Time= O, Off Time = F. Equation: D = O / (O + F) x 100. For example: ICI’s standard SD model has a 5 second cycle time and is rated @ 25% Duty Cycle. Witryna29 gru 2024 · Duty cycle is the percentage of time that a machine will safely operate (or weld), within a certain time period, at a given amperage. For example the Weldforce WF-205MST multi-function welder has a duty cycle of 200 Amps @ 30%. This means that it will operate at 200A for 3 minutes within a 10 minute time period. robot modal analysis
