Machine inertias are harder to define, since each manufacturer uses slightly different geometry (and possibly materials) - the inertia can be found using waross' calculation. Once you have the inertia OF THE DRIVE TRAIN, you can figure out how long it will take to accelerate based on the ...

Based on the one-dimensional field theory for linear induction motor (LIM), the analytical model of two adjacent series motors was built, then the relationships between spacing and traction, current, voltage, etc., were derived. The theoretical calculation results were directly verified by finite ...

the detection and classification of bearing faults in an induction motor are performed using machine learning techniques. The current signal from two different phases is recorded for three motor conditions: healthy, inner race fault and outer race fault. The statistical features are then applied for ...
An ACI motor can be led to steady state by simple voltage fed, current controlled, or speed controlled schemes. The scalar variable can be manipulated after obtaining its value either by direct measurement or calculation, and can be used in both open loop and closed loop feedback formats. ...
A switching control portion(50) is formed with a switching lookup table(52) and a voltage vector selection portion(51) in order to output a gating signal of a 3-level inverter(120). A calculation portion(70) detects a voltage of an inverter. A current sensor portion(80) detects current ...
The proposed PTC method is based on mathematical equations, which allow minimization of torque error and calculation of a relevant reference voltage to establish a better dynamic response in the transient state and accurate control performance in the steady state. Excellent steady-state performance and...
