Advantages of integrated encoder solutions from Kübler
ROBUST
Resistant and sensitive to external influences
SIMPLE
Simple integration directly on the shaft or in the housing
PRECISE
Precise angle measurement even at high speeds
FLEXIBLE
Wide choice of interfaces and resolutions
Integrated encoder solutions with diametrical magnets – Design
- Diametral magnet - north and south poles are arranged on the side of the cylinder / the magnet is connected to the motor shaft
- Magnetic field sensors with signal evaluation - Energy harvesting technology for multiturn detection
- Shield plate for EMC protection against the motor brake
Functionality
When the magnet rotates with the shaft, the magnetic field changes in the plane of the direction of rotation. Directly below or next to the magnet, the sensors record the magnetic field changes as X and Y components, which are converted into sine and cosine signals.
The exact rotational position (angle) is calculated from these signals with a resolution of several thousand steps per revolution. Optionally, an energy-harvesting chip can store the number of revolutions if the power supply is interrupted.
power supply is interrupted.
