Hengsler magnetic encoder manufacturer

Hengsler magnetic encoderAnother frequently criticized drawback is its slow response speed, which cannot handle the position feedback of high-speed moving loads. In addition, its (relative to optical encoders) lower accuracy and resolution make magnetic encoders less suitable as integrated position feedback components in servo motors; In addition, as a servo encoder, there is another problem that must be solved, which is multi turn position feedback A typical Hengshler magnetic encoder can achieve a resolution of 13 bits per coil, although a certain manufacturer has already achieved a resolution of 17 bits per coil in this regard, this is only a relatively ordinary level achieved by optical encoders. So, the current magnetic encoders are more suitable for application scenarios, perhaps for some common position and speed detection links, such as the Hensler magnetic encoder, rather than high-performance transmission and motion control systems, especially transmission control loop feedback.

IfHengsler magnetic encoderWhen technology is applied to the rotational position feedback of motors, the permanent magnet of the encoder can be directly installed at the end of the motor shaft, eliminating the need for transitional bearings (or couplings) in traditional feedback encoders and achieving non-contact position measurement. This reduces the risk of encoder failure (or even damage) caused by mechanical shaft vibration during motor operation and helps improve the stability of motor operation. The Hengshler magnetic encoder also has some specific shortcomings. For example, it is susceptible to electromagnetic interference and requires compensation and protection measures to avoid temperature drift.

Hengsler magnetic encoderIt has the same mechanical shaft and housing structure, but at the same time, its position detection mechanism appears very simple, just a small magnet installed at the end of the mechanical shaft to rotate with the shaft and a PCB circuit board at the end of the encoder. If a magnetic field is applied in a direction perpendicular to the plane of an electrified conductor, the charge flowing on the conductor will experience a deviation in its path due to the Lorentz force induced by the magnetic field. The Hengshler magnetic encoder, based on the left-hand rule learned in high school physics class, can determine the direction of deviation when charges flow, and the direction of deviation when positive and negative charges flow in a magnetic field is opposite. That is to say, when a current flows through this flat conductor in a magnetic field, its positive and negative charges will respectively pass through it along two paths on the left and right.
