Defining the terms.
|Up||ADC supply voltage||A supply voltage is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters|
|UО||ADC reference voltage||A voltage reference is an electronic device that ideally produces a fixed (constant) voltage irrespective of the loading on the device, power supply variations, temperature changes, and the passage of time. Voltage references are used in power supplies, analog-to-digital converters, digital-to-analog converters, and other measurement and control systems|
|m||ADC digital capacity||The digital capacity of the converter indicates the number of discrete values it can produce over the range of analog values. The resolution determines the magnitude of the quantization error and therefore determines the maximum possible average signal to noise ratio for an ideal ADC without the use of oversampling|
|g||Acceleration of gravity||The standard acceleration due to gravity (or standard acceleration of free fall), sometimes abbreviated as standard gravity, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth (9.80665 m/s2).|
|l||Measurement arm (lever)||A measurement arm (lever) is a rigid body capable of rotating on a point on itself.|
|R||Resistance value of the tensoresistive bridge||A tensoresistive bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit|
|SC||Sensitivity of the effort sensor||A sensor's sensitivity indicates how much the sensor's output changes when the input quantity being measured changes|
|ω||Free natural frequency||Natural frequency is the frequency at which a system tends to oscillate in the absence of any driving or damping force|
|K1||Coefficient of the conversion of the tensoresistive transformer||A proportionality coefficient of linear dependence of input (Mp) and output (NMy) signals|
|S||Slip||Slip is defined as the difference between synchronous speed and operating speed, at the same frequency, expressed in rpm or in percent or ratio of synchronous speed|
|J||Moment of inertia of the moving part of the electric motor||The mass moment of inertia measures the extent to which an object resists rotational acceleration about a particular axis, and is the rotational analogue to mass|
|p||Number of pole pairs||Any node of a circuit that is available for connection to an external circuit is called a pole (or terminal if it is a physical object). The port condition is that a pair of poles of a circuit is considered a port if and only if the current flowing into one pole from outside the circuit is equal to the current flowing out of the other pole into the external circuit|
|i||Transmission value of the reductor||Transmission ratio is formally considered as the ratio of the number of the wheel teeth to the number of gear teeth|
|η||Efficiency coefficient||Efficiency coefficient − the efficiency characteristic of the system (devices, machines), or in respect of the conversion of energy transfer. It determines the ratio of useful energy used to the total amount of energy received by the system (device, machine)|
|ωr||Angular speed||The angular speed is defined as the rates of change of angular displacement and is a vector quantity (more precisely, a pseudovector) that specifies the angular speed (rotational speed) of an object and the axis about which the object is rotating|
|МCC||Moment of eccentricity of the clutch coupling||A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded
Eccentricity – numerical characteristic of a conic section, showing the extent of its deviation from the circle
|Ts||Electromagnetic time constant of the stator||Electromagnetic time constant of the stator is associated to the cutoff frequency of the stator field and the critical slip value|
|МP||Torque of the electric motor||A torque motor is a specialized form of electric motor which can operate indefinitely while stalled, that is, with the rotor blocked from turning, without incurring damage. In this mode of operation, the motor will apply a steady torque to the load (hence the name). A torque motor that cannot perform a complete rotation is known as a limited angle torque motor|
|SP||Sensitivity of means of measurement||The sensitivity of means of measurement – measuring means property defined by the ratio of change of the means of the output signal (NMy) to the calling of his change of the measured value (МP).|
|ΔNJ||Multiplicative error||Multiplicative called error linearly increasing or decreasing with the increase of the measured value (the error is proportional to the measured value)|
|ΔNaJ||Additive error||Additive error called error constant at each point of the scale|
|uBinst||Uncertainty of type B||Uncertainty of type B is a component of uncertainty to which the statistical evaluation methods cannot be applied. In such cases, use other known methods (scientific judgments, which are based on accessible information about the possible changes of the measured value)|
