Hall current sensors, also commonly known as current transformers or current transformers, are devices that measure the current flowing through a wire by using a magnetic field to detect the current and generate a proportional output.Principle of Hall current sensorWhat is it? They are used togethe...
What is the principle of a deflection magnetometer?Magnetic Field:The magnetic field is defined as the region near a magnet bar or an electric charge and exerts a magnetic force in the region. It is a vector field that shows the magnetic effects in electrical charges of magnetized materials....
So, we will try to explain the principle of torque generation of a cored motor from two aspects. (A) Explanation Based on the Tension of Magnetic Field Lines The BLI law cannot explain mutual attraction or repulsion of magnets, or the force with which a magnet attracts nails. That is, fo...
field. The winding on the rotor is a closed loop conductor, located in the rotating magnetic field of the stator, which is equivalent to continuously cutting the magnetic induction line of the stator. According to Faraday's law, when a part of a closed conductor cuts through a magnetic ...
Accurate control of the instantaneous torque produced by a motor is required in high-performance drive systems, e.g., those used for position control. The torque developed in the motor is a result of the interaction between current in the armature winding and the magnetic field produced in the...
The basic working principle of the stepper motor is the following: By energizing one or more of the stator phases, a magnetic field is generated by the current flowing in the coil and the rotor aligns with this field. By supplying different phases in sequence, the rotor can be rotated by...
