BH-0.66 II series current transformer is new in its magnetic circuit design, advanced in compensation method, exquisite in technology, safe and reliable in performance, small in appearance, and generally used for control, protection and measurement.
The magnetic circuit design with an optimized layout of the high-sensitivity differential hall IC and magnet realizes zero-speed(ultra low-speed) rotation detection at high precision while suppressing jitter, even in the partial region such as during restarting after idling stops or when the throttle opening is small.
The magnetic resistance for each part making up the magnetic circuit is obtained using integral calculations in the magnetic circuit method often used in simplified design, but the number of calculations greatly increases for the parts required to gain higher accuracy if the geometry is complicated.
We moved to Kumagaya area in 2018, in order to have a closer collaboration with our production factory. We will fulfill our expected rolls as the pioneer of the permanent magnet development, utilizing our powder metallurgy material technology, magnetic circuit design and analyze technology.
To make the best use of a permanent magnet fully enough, an optimum design of magnetic circuit must be necessary, and one should be skilled with the characteristics etc. of designing of magnetic circuit technique and a permanent magnet for that.
An analysis accounting for the eddy currents is also possible by specifying the electric conductivity of the conductors to handle phenomena produced by eddy currents in conductors while including the effects of eddy currents in the magnetic circuit method is difficult because the distributions cannot be calculated.
For magnetic circuit confirmation, it is the most basic usage method for FEA, but seeing the flow of magnetic flux line density contour plots and flows of magnetic flux lines means that one is visualizing the magnetic circuit itself and confirming it.
The Neutral Current Eliminator(NCE) consists of harmonic excluder which have special magnetic circuit structure and its aid-part, it can effectively eliminate 3rd harmonics and reduce input and output neutral current to 0 A.
In addition, the permanent magnet generator magnetic circuit structure varied, leakage magnetic circuit is very complex and large proportion of leakage magnetic flux, ferromagnetic material part is relatively easy to saturation, the magnetic guide is non-linear.
In addition to the semiconductor-related field, this large-size magnetic circuit is expected to be used in application fields where a stable, strong magnetic generation source is required, such as for high-end HDD drive heads, medical devices and for basic research uses.
When driving a larger diaphragm, in order to avoid air within the enclosure acting like a strong spring to stop the movement of the diaphragm, the vibration system is made heavier and the magnetic circuit larger to reduce the spring-like effects of the air pressure to a negligible level, a mechanism that allows the low-frequency reproduction limit to be lowered even further.
The motor has been designed with a structure that fully utilizes the rotor's external diameter and effective maximization of the magnet cubic content in mind, and high-performance magnet manufacturing technology has been combined with proven DC brush contact point technology and magnetic circuit design techniques, to develop a DC brush motor with double the torque relative to motor cubic content compared with existing motors.
Design of Magnetic Circuits Tokyo Ferrite Mfg. Co.
Design of Magnetic Circuits.
The relation between unwanted vibration and the magnetic circuits of the motor is examined and extrapolated to improve the structural design of the motor, reducing vibration and noise.
In particular, the magnetic circuits, the cores and the winding stand out as requiring special attention when designing thinner motors.
On the other hand, detailed magnetic circuits are designed for motors using ideal controllers.
I work on rare earth and non-rare earth permanent magnet motors and non-permanent magnet motors(for example, brushless double-fed and reluctance motors), generalized magnetic circuits, and magnetization especially post-assembly magnetization techniques.
To generate a strong magnetic field in a permanent magnet-type magnetic circuit, a complex magnet alignment is required, and accordingly, the production of such magnetic circuits has been difficult to achieve. Until now, the production of small-size magnetic circuits with an inner diameter of about 100mm was the limit.
For example, conventionally we have considered how combustible energy and electric energy can be mixed using two motors and gears; however, we now think about integrating the functionality of gears and motors and consider things like"If we configure the magnetic circuits this way, we can make this possible.
