cylinder-shaped magnet, its recommend adopt NdFeB (neodymium iron boron) or SmCo (SmCo) make, in order to improve certainty of measurement, the deviation of the center of this contactless magnetic rotary encoder and the axis of bipolar magnet 5 is less than or equal to (radius) 0.45mm, for the ease of installation and removal, be beneficial to daily maintenance, installing plate 7 and backing plate 8 is also provided with in the present embodiment, IC circuit board 4 is fixed by screws on installing plate 7, installing plate 7 is bolted on sewing machine body 1, and backing plate 8 between sewing machine body and installing plate, and is also fixed with the lid 9 that can cover installing plate 7 on sewing machine body, this lid plays the effect of protection, avoids dust, water or other foreign matters enter and affect or damage IC circuit board.
Angle detection device in the application also can adopt optical encoder to substitute.
Be described further contactless magnetic rotary encoder below, that this contactless magnetic rotary encoder adopts is AS5040.
AS5040 is a contactless magnetic rotary encoder, for accurately measuring the angle in whole 360 °.This product is a SOC(system on a chip), incorporates integrated form Hall element, AFE(analog front end) and data-signal processing capacity in single package.When taking measurement of an angle, only need be equipped with 1 bipolar magnet just rotated in the heart in the chips simply, this magnet can be arranged on above or below IC certainly.This measurement of absolute angle mode can the Angle Position of indication magnet immediately, and its resolution ratio reaches 0.35 °, and namely often enclose 1024 positions, digitalized data can provide with the form of serial bit stream or pwm signal.In addition, the increment type of user-programmable also can be provided to export, make this chip be applicable to very much replacing all kinds of optical encoder product.AS5040 built-in voltage adjuster, under allowing it to be operated in 3.3V or 5V supply voltage.It is complete SOC(system on a chip); There is system scheme flexibly, absolute value Serial output, PWM can be provided to export and increment output simultaneously; Owing to adopting non-contact type detection mode, the application harsh to working environment is ideal; And magnet positions can be tolerated depart from and air gap change conditions, temperature-compensating need not be carried out, without the need to calibration simultaneously.
Pin explanation is done below in conjunction with Fig. 4 and table 1;
Table 1
In table: DO_OD: numeral exports, open-drain S energization pins
DO: numeral exports the input of DI numeral
DI_PD: numeral input, is with drop-down DO_T numeral output/tri-state
The input of DI_PU: numeral input, band pull-up ST Schmidt trigger
Pin 7,15 and 16 is energization pins, and pin 5,13 and 14 is used by inside, and must floating.
Pin 1 and pin 2 are changes of magnetic field instruction pin, MagINCn and MagDECn (when the spacing of magnet and device changes, magnetic field intensity is by enhancing or weaken).These outputs can be used to detect effective magnetic field range.In addition, these instruction pins also can be used to realize non-contact type push button function.
Pin 3,4 and 6 is delta pulse output pin.The function of these pins can be configured by programming One Time Programmable (OTP) register.
AS5040 adopts CMOS standard technology to produce, and have employed a kind of rotatory current Hall technology, the Distribution of Magnetic Field (consulting Fig. 5) on detection chip surface.Built-in Hall element distributes around the center of chip, and produces the voltage that one characterizes chip surface magnetic field.By ∑-Δ Analog-to-Digital Conversion Technology and Digital Signal Processing (DSP) algorithm, AS5040 can provide accurate high-resolution absolute value angle information.In order to realize this function, have employed CORDIC (CORDIC) algorithm to calculate the amplitude of angle and Hall array signal.The digital information of DSP also for providing MagINCn and MagDECn to export, indicate the magnet that uses near or away from the motion conditions of chip surface.AS5040 can detect the orientation in magnetic field, and calculates 10 binary codings.Synchronous serial interface (SSI) can be passed through and read this encoded radio.In addition, pin 12 (PWM) the also exportable pulse-width signal representing absolute value angle.
Below detection method is briefly explained:
The girth of tugboat: l=2 π r, r are the radius of tugboat; L is the length that tugboat rotates one week car slide fastener; If specify car zipper length to be L, then the rotation number of turns n=L/l needed for rotating shaft, the rotational angle of required detection is n*360 °, namely when car zipper length is L, only need set the rotational angle of rotating shaft:
N=180*L/ π r.
