Abstract
The utility model discloses a motor coding device which includes a power-supply interface, a coder, a data interface and a controller. The coder is connected with the power-supply interface, the data interface and the controller. The coder adopts a magnetic rotary coder. The motor coding device is simple in design, capable of realizing measurement of rotating angle and speed of a motor in a real-time manner and replacing a photoelectric coder, low in cost and reduced in cost.
Description
Technical field
The utility model belongs to motor monitoring field, is specifically related to a kind of motor code device.
Background technology
Widely used motor encoder is take absolute type rotary photoelectric encoder as main in the market, because its each position has uniqueness and anti-interference, various industrial control fields have been widely used, on absolute encoder optical code disk, be carved with multiple tracks light code line, per pass groove is successively with mode layouts such as 2 lines, 4 lines, 8 lines, 16 lines, encoder reads the logical, dark of per pass groove, obtain one group from 2 zero degree side the 2 unique scale codings to 2 n-1 power, and then reflect rotational angle and the velocity information of motor.Absolute type photoelectric encoder is more because of its output figure place, and each output signal must be guaranteed to connect fine, and compared with isolating under complex working condition, stube cable core number is many, brings thus inconvenience and reduces reliability.Due to corresponding circuit design more complicated, materials require higher simultaneously, and the price of photoelectric encoder is also always high.
Summary of the invention
The purpose of this utility model is the defect existing in prior art in order to solve, and a kind of simple, effective motor code device of instead of optical photoelectric coder is provided.
In order to achieve the above object, the utility model provides a kind of motor code device, comprises power interface, encoder, data-interface and controller; Described encoder is connected with power interface, data-interface and controller respectively; Described encoder adopts magnetic rotary encoder.
Further improvement of the utility model is: above-mentioned encoder comprises magnetic rotary encoder and low-pass filter circuit; Described low-pass filter circuit is connected with described magnetic rotary encoder.Wherein encoder adopts programmable magnetic rotation coding device AS5040.
Above-mentioned controller comprises control chip and low-pass filter circuit; Described low-pass filter circuit is connected with described control chip.Wherein, control chip adopts STC15F104.
The utility model has the following advantages compared to existing technology: the utility model motor code device simplicity of design, and the energy rotational angle of real-time implementation to motor and the measurement of speed, effectively instead of optical photoelectric coder, and cost is low, cost-saving.The speed of rotation that the utility model motor code device is measured can reach 10000rpm, strong interference immunity, and stable performance, is applicable to being extensively generalized to automobile application and industrial control field.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the utility model motor code device;
Fig. 2 is encoder in Fig. 1 and the connecting circuit figure of controller;
Fig. 3 is the linear relationship of the utility model motor code device simulation output and angle value.
specific implementation method
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, this motor code device has comprised 4 parts: encoder, controller, data-interface and power interface.Encoder is connected with controller, power interface and data-interface respectively.In conjunction with Fig. 2, encoder adopts coding chip to connect low-pass filter circuit, and controller adopts control chip (as STC15F104) to connect low-pass filter circuit.Coding chip adopts a kind of touchless magnetic rotary encoder (as AS5040), integrated Hall element, AFE (analog front end) and data-signal disposal ability on sheet, therefore only need to set coded program, chip and motor position are correctly installed, can realize the measurement of angle and speed.This coding chip itself has U, V, W signal and pwm signal, and pwm signal is carried out to simple low-pass filtering design, directly by analog voltage, shows the size of angle, as shown in Figure 3, directly substitutes photoelectric encoder in the market.
During use, the motor shaft that needs are measured be correctly arranged on coding chip directly over, require deviation within the scope of RC 0.25mm, simultaneously the distance of motor shaft range coding chip is that 0.5mm is to 1.8mm.
When motor rotates, the Magnetic Field on coding chip surface will change, and chip adopts Hall sensor array to sample to the magnetic field that is distributed in device package surface.In inside, by signal processing, obtain corresponding velocity information and angle information, by data-interface, transmit out.
