[introduction] the position with accurate automation system exact need is measured, it is especially in the industrial application such as the robot, want to realize accurate electric machinery control, need the measurement with accurate height. Inductive type encode is had high accuracy, tall stability and other the advantage that has appeal.

Ansenmei (Onsemi) developed brand-new rotate sensor of type industry position, combined high accuracy, high rate and tall stability — measure feeling of inductance type place promotion to arrive a new standard, apply to industrial application. This innovation plan used patent inductance type sensor to design a technology, make its can offer taller than sensor of position of other inductance type precision.

Graph 1. The mechanical arm on industrial product line

Framework of new-style double inductance is a kind of current method that can be used at all sorts of machinery to measure. Basically use at buy of perceptive dislocation coming back (with speed) , this technology can offer the resolution of 20-bit. Configuration of all sorts of sensor dimension option can apply at what a lot of differring for choosing.

Use sensor of a 38 millimeter to be in 6, can achieve when 000 RPM rotate speed + / – the precision of 50 horn second. In sacrifice the circumstance of trifling precision falls, NCS32100 is supportable be as high as 100, the rotate speed of 000 RPM.

Inductance type sensor gets all sorts of pollution or disturbing influence not easily, include liquid, bilge and dirt, magnetic field, EMI and intense vibration. NCS32100 suffers the effect of mechanical vibration not easily also, OK and divisional rotor arrives to the translation of stator and rotor the whirl of stator. For example, it is OK and divisional whirligig (be measured) the vibration with X, Y or Z axis (can according to demand eliminate) .

NCS32100 is offerred tall compositive degree, this makes its are become simple and the solution that uses easily. Does it include to contain shine put the Arm that configures a setting with memory? Cortex? – M0+ processor. It still contains compositive and can the program of fast ego calibration (produce machine down time with decreasing as far as possible) , make its can compensate the asymmetry sex of PCB. Need rotor roll only, can finish this kind of calibration inside 2 seconds. It has a process designing interface that uses easily, can combine all sorts of sensor and PCB to use, realize different design, appearance, dimension and appearance element, in order to obtain the biggest design flexibility.

This plan is OK and immediate output the position and speed with digital format, need to give these information from the derivation in primitive imitate signal no longer. NCS32100 can reduce requires other component amount, and design time and risk. The plan that is based on NCS32100 can be finished with 12 component, and similar 38mm optics coder needs 100 many component. Comparative these two kinds of solutions, the sensor that is based on NCS32100 can reduce the BOM of an amount class.

Graph 2. Double inductance rotates type position sensor

Agile mechanical norms allows to come true below actual condition + / – the precision of 50 horn second. For example, in NCS32100 referenced design, rotor arrives for 0.1mm to the air gap of stator 0.5mm, rotor does not exceed 0.5 degrees to the gradient of stator, this also can be accepted completely. Offer besides referenced design 0.1 to 0.5mm besides, sensor can realize different air gap, 1mm is a common typical air gap. In addition, ego calibration does not need referenced coder; Need to ensure rotor rotate speed is mixed in 100 RPM only 1, between 000 RPM.

Of height can configure a gender to make its can be used together with all sorts of PCB sensor, make terminal user can be configured change its solution with difference.

The front of NCS32100 has one each to move gain amplifier (AGC) with converter of a compositive modulus (ADC) . Compositive Arm? Cortex? – M0+ small controller includes to be not break a gender easily to shine put (NVM) use at with with advocate processor corresponds can configure interface.

Design personnel can choose a series of optional functions the function with raising NCS32100 further, include the defer extrapolate, low wave that connect filter (LPF) , open circuit coil detects and clear automatically. In addition, ansenmei earlies childhood to design and be evaluated for reference board, personnel implementation is evaluated quickly and put in the market in order to help a design quickly.

In the industrial application that has a lot of fast and mobile machine, accurate positional perception is indispensable. Accuracy, speed, compositive degree, use gender, stability and the couple of interference rejection sex that get all sorts of pollution or disturbing influence not easily easily, make NCS32100 makes the solution that has an advantage very much.

The whirl that installs dark beauty sensor of type industry position is industrial application to rotate mediumly feeling measure offerred outstanding solution. The new plan that understanding more surveys about NCS32100 and feeling of inductance type place, implementation is brand-new coder of buy of high accuracy dislocation coming back.
