Rotary encoder parameters professional term definition

by:HENGXIANG     2020-11-07
When we choose our rotary encoder will have some professional term of parameters, the terminology is what meaning? After we learn about the clearer positioning the rotary encoder parameters we need to be more accurate. Round of rotary encoder output pulse number/the number of pulses output by a circle of hair, for optical rotary encoder, often with the inside of the rotary encoder grating groove for the same ( Can also be used in the circuit of output pulse number added to the slot number 2 times 4 times) 。 Resolution of rotary encoder resolution said the spindle rotation week, read the location data of maximum score, etc. Absolute value type is not in the form of a pulse output, while in the form of code is the location of the spindle ( Perspective) 。 Unlike incremental type, is equal to the incremental type 'output pulse/roll. Grating optical rotary encoder, the grating has two kinds of metal and glass. Is made of metal, has light hole groove; Is made of glass, it is in the glass surface coated with a layer of shading film, here there is no clear line ( Slot) 。 Slot number less, can be used on the metal plate punching processing or grooving corrosion method. In impact resistance type using the metal grating encoder, it doesn't impact resistance compared with the metal grating, so on use, please note that don't impact directly on the encoder. Maximum response frequency is the maximum number of pulse response reaction in the 1 second ( Example: maximum response frequency to 2 KHZ, which is 1 seconds to 2000 pulse response) The formula is as follows: maximum response speed ( rpm) /60× ( Pulse number/roll) = output frequency Hz maximum response speed is the highest speed of response, happened under the speed pulse response formula is as follows: maximum response frequency ( Hz) / ( Pulse number/roll) × 60 = shaft RPM speed output waveform output pulse ( Signal) The waveform. The output signal, the output of the phase difference between two phase two output pulse waveform of the relative lag. Output voltage output pulse voltage. The output voltage will change because of the change of output current. Various series of output voltage, please refer to figure starting torque output current character makes in the stationary state of the encoder shaft rotation necessary moment. Usually run in the moment than the starting torque is small. Axis allow load additive on the axis of maximum load, which has two kinds of radial and axial load. Radial load for shaft is vertical, loading and eccentric Angle and so on; Axial load for shaft is horizontal, stress is associated with the force of push-pull shaft. The two forces affect the size of the shaft mechanical life of the axis of rotation inertia moment of the value of moment of inertia and resistance to rotational speed change speed mechanical load limit of the speed instruction encoder. If you exceed this limit, will have a negative impact on the service life of the bearing, the other signals may interrupt. Gray code gray code is advanced data, because it is a unit of distance and cyclic code, so it is safe. Each step is only one change. The data processing, gray code must be converted to binary code. Working current channel allows load current. Working temperature parameters mentioned in the table data and tolerance, in this temperature range is guaranteed. If a little higher or lower, the encoder will not damage. To recover when temperature and can achieve technical specification work voltage power supply voltage of the encoder. Shanghai electronic products co. , LTD. , specializing in the production of rotary encoder for 27 years, as a 26 year old encoder manufacturers, in addition to have a lot of research and development manufacturing experience, our strength, the factory has advanced production equipment and testing equipment, the quality of new and old customers to order, delivery, service all can rest assured! We can according to customer demand parameter to customize the encoder, and encoder models complete, can perfect replacement brand encoder, both at home and abroad to find the encoder don't have to travel, looking for a rotary encoder manufacturers electronics is the most wise choice!
