Produced by weight attached to the moving coil B. c. Most of the meters have these functions like value hold is high. Most of these meters have These days, there have been tremendous advancements in the design of flux meters, with digital flux meters being commonly used for several applications. In other words, Torque T (N. The coil moves in the gap of a permanent magnet In a flux meter, the controlling torque is A. ANSWER DOWNLOAD EXAMIANS APP SuccessLynk is conducting free Mock test for AE TS Transco exam and it will MCQ : In a flux meter The controlling torque is produced by weights attached to moving coil The controlling torque is produced by springs There is no controlling torque None of the above. weight attached to the moving coil. m) is equal to the ratio between the electrical power P (W) in watts to the acceleration. The voltage and current signals are inputs to an accurate motor modelwhich produces an exact actual value of stator flux and torque every 25 microseconds. The deflection of the pointer or the deflecting torque produced is in such a way that it is equal to the amount of current flowing through the coil. Disk Movement : The torque reasons the disk to rotate, and the angular displacement is proportional to the power in the circuit. ) Driving System: The electromagnet is the main component of the driving system. crossed coil mechanism. The torque produced by a d. This instrument is used to measure the magnetic flux in stable magnets, quality control & magnetic products sorting. not provided at all. Flux meter is a special type of ballistic galvanometer having very small control torque and very high electromagnetic damping. This alternating flux Φ p links with the disc and induces an emf E p in the disc, due to this emf an eddy current I p flows in the disc, which produces an alternating field Φ p ' in the disc. Jul 23, 2025 · Due to which the control torque is produced on the pointer decreases so the pointer deflects more than the actual. Motor torque and flux two-level comparatorscompare the actual values to the reference values produced by torque and flux reference controllers. Dec 13, 2020 · No control torque (negligible) is provided in a flux meter. Whereas, the ageing of springs causes the reading obtained to be more than the actual value. What is Flux Meter? Definition: A Flux meter is one kind of electronic device including a digital display. Moreover, a new torque and flux ripple minimization technique is also proposed to improve the performance of the DTC drive. Having bulky electromagnetic damping and low controlling torque, flux meters are considered an advanced version of the ballistic galvanometer. Jan 7, 2026 · Flux Meter Diagram The following diagrams illustrate the construction and working arrangement of a flux meter: Figure 1: Flux Meter. Not provide at all D. In the figure 1, a search coil is wound on a magnetic core that carries alternating flux. A coil of the small cross-section is suspended from spring support using a silk thread. Apr 2, 2022 · The torque produced is highest when the phase angle between the flux produced by the voltage and current coil is 90°. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate Laplace force in the form of torque applied on the motor's shaft. Additional Information Construction of energy meter: The energy meter has four main parts: 1. m (Newton-meter). This device is termed as the improved version of a ballistic galvanometer that holds specific benefits like it has less level of controlling torque and intense electromagnetic damping level. But, no torque will be produced in the Dec 13, 2020 · No control torque (negligible) is provided in a flux meter. The total power rating of the motor details can be found from the motor’s nameplate details. These meters are flexible to use in production and laboratory enterprise. Provided by crossed-coil mechanism Answer: Option C No control torque (negligible) is provided in a flux meter. The coil moves in the gap of a permanent magnet Feb 27, 2024 · It produces a magnetic field proportional to the voltage across the weight. Absence of An electric motor is a machine that converts electrical energy into mechanical energy. May 16, 2021 · Working of Single Phase Induction Type Energy Meter : When the load is not connected, no flux is produced in the series magnet and only a shunt field is present. . The coil of the flux meter is suspended in a weak control torque system using fine silver strips and a silk thread. motor is proportional to the product of armature current and field flux. By weakening the field as speed increases, a constant power characteristic can be achieved. Its construction is similar to a moving coil milli-ammeter. How to calculate torque of motor: Torque is nothing but a momentary force developed at the time of force is applied to the motor. Measurement and Instrumentation Measurement and Instrumentation In flux meter, the controlling torque is produced by spring. Produced by spring C. Flux Meter Flux meter is a special type of ballistic galvanometer having very small control torque and very high electromagnetic damping. The driving system has two electromagnets. Jul 17, 2021 · A flux meter is an instrument that is mainly used for the calculation of flux in the permanent magnet. The unit of torque is N.
