ALGORITHM FOR DETERMINING THE TORQUE OF ELECTRIC MOTORS USING INDIRECT MEASUREMENT METHODS

Indirect torque measurement methods can be performed in a variety of ways, depending on the specific situation and available tools. One such way is to measure displacement, or speed rotation shaft use this information calculate moment using inertia equation. For this, it necessary know angular acceleration, which measured gyroscope accelerometer. Another voltage current electrical circuit connecting motor power source by determining electric motor. However, indirect measuring torques motors are based other physical parameters that correlate with torque, as current, voltage, frequency, etc. These often used because their cost-effectiveness ease implementation, but they have some drawbacks. In particular: usually less accurate than direct depend mathematical models correlations between different parameters, may imprecise incomplete; influenced external factors, affect accuracy measurements; calibration devices carried out laboratory conditions, so results not reflect real operating conditions; determine non-linear. This lead errors measurements, especially at high low values; do provide feedback about delays process regulation control. critical for applications where fast control essential; efficient unsuitable types applications. example, when high-frequency multiphase motors, sufficient stability measurements. The article examines algorithms rotational methods. An analysis characteristics according energy data was out. possibilities determined functional dependence its shaft. components studied simulation given. velocity acceleration out, role these determination investigated. A two-channel network-type system proposed, allows collection visualization, one channel power, speed.
