How to use a SSI encoder S7.

Sep 30, , What I"m trying to do is build a dyno to calculate the horsepower output of motorcycles. So the rear wheel sits on a heavy metal drum and is accelerated to full speed, some simple math allows you to calculate the horsepower based on the acceleration of the drum knowing its interia. So the mechanical side of things is built and I"ve got an encoder connected to the drum to give me TTL pulses either once per revolution or fifty times. The encoder is a Hengstler RI It"s pretty simple really, but the problem is speed and accuracy. As I"m comparing such small times they need to be quite accurate and because the time between pulse is so small a PC is useless for reading the data.

You can see it visually in the figure on the left. There are two sets of stripes, one within the other. The track on the inside is set apart from the outside track by 90 degrees.

The encoder is a high quality Bourns rotary encoder, with 18 clicks per revolution (20° rotation per click). The encoder shaft is" (mm) diameter with a flat. All .

The AD is a chip that can produce a sinusoidal wave from about 1hz to 40mhz. Without going into too much detail you are required to send a set of serial or parallel data to the chip to set the frequency. However it has been hard to find a good AD Pinout so here you go. For me, the easiest way to manage the AD is with an Arduino Uno. I have been playing with the Arduino for only a couple of months and I already have found it to be a fantastic development platform. A little quick work with a protoboard and I have a nice working VFO.

You can watch my video on YouTube showing how it works.

Unlike the existing VEX Shaft Encoders, they connect to the Cortex Microcontroller using the I2C port and provide feedback directly from the motor with the added benefit of not hogging up your digital ports. These encoders will allow you to identify and control how fast the motors spin, how far the robot travels, and what direction it should move. I2C ports allow multiple devices to be connected in a manner frequently referred to as daisy-chaining: The Integrated Encoder Modules support this by having built-in sets of input and output pins.

A 4-wire cable connects the Cortex to Motor 1, another 4-wire cable connects Motor 1 to Motor 2, another 4-wire cable connects Motor 2 to Motor 3, and so on. Some of the most visually noticeable changes are in the Motors and Sensors Setup.

Measuring angles with rotary encoders Mounting variants In rotary encoders with integral bearing and stator coupling, the graduated disk of the encoder is connected directly to the shaft to be measured. The scanning unit is guided on the shaft via ball bearings, supported by the stator coupling. During angular acceleration of the shaft, the stator coupling must absorb only that torque resulting from friction in the bearing, thereby minimizing both static and dynamic measuring error.

Moreover, the coupling mounted on the stator compensates axial motion of the measured shaft. Other benefits of the stator coupling are: Simple mounting High natural frequency of coupling Hollow-through shaft possible Rotary encoders with integral bearing that are conceived for separate shaft coupling are designed with a solid shaft.

The recommended coupling to the measured shaft compensates radial and axial tolerances.

John Deere supports the usage of bio diesel. Simply open the drain valve on the bottom of the separator and drain-accumulated water. Engine access Open hood on 9R The one-piece tilt hood design provides side shields and guards for additional engine compartment protection.

If you’re trying to decide between using an encoder and hacking apart your keyboard, I would definitely recommend an encoder. If you order prewired connectors as I did, you should be able to do the electrical hookup in an hour or so.

Concept of rotor excited resolver Rotor excitation and response The most common type of resolver is the brushless transmitter resolver other types are described at the end. On the outside, this type of resolver may look like a small electrical motor having a stator and rotor. On the inside, the configuration of the wire windings makes it different.

The stator portion of the resolver houses three windings: The exciter winding is located on the top; it is in fact a coil of a turning rotary transformer. This transformer induces current in the rotor without a direct electrical connection, thus there are no wires to the rotor limiting its rotation and no need for brushes. The two other windings are on the bottom, wound on a lamination.

They are configured at 90 degrees from each other. The rotor houses a coil, which is the secondary winding of the turning transformer, and a separate primary winding in a lamination, exciting the two two-phase windings on the stator. The primary winding of the transformer, fixed to the stator, is excited by a sinusoidal electric current, which by electromagnetic induction induces current in the rotor.

What is the HDHomeRun? It connects to your antenna or cable line depending on model and takes the digital TV signals available there and makes them available to your PC, tablet, smartphone, game consoles, and other devices over your existing home network. What is the difference between the different models? It uses a CableCARD that you rent from the cable provider to get access to all the channels that are part of your cable subscription.

It has 3 tuners, allowing you to access 3 channels at once. It has 4 tuners, allowing you to access 4 channels at once.

So you"ve just received your Zero Delay Arcade USB Encoder and its time to wire it up! Start by getting the USB Encoder PCB board and take note of the connections. We are going to wire up the Joystick first, so grab that and the ribbon cable. Plug one end of the ribbon cable into the joystick port, then plug the other end onto the 5 pins on the joystick.

Model Receiver Parts ldentification Notes We rely on you to know already what a resistor, transistor, lC"chip" and other common electronic parts"look like. Both the back and inside front covers of this manual provide some light-hearted help on basic parts identification. Each assembly step provides useful help in identifying any part, whether by shape, color-code, manufacturer"s markings, or other description.

The Zener, and Varactor diodes must be identified exactly. Our protocol is to identify those in picofarads up to 99 pF simply as 1 pF or 33 pF, etc. There may be one letter to identify temperature characteristics e. Building Electronic Kit Projects: Both this manual and the engineering discipline for this receiver were done with YOU very much in mind. Here"s what is important: To get a good fit of the LED"s and 3- digit displays, you"ll be handling the front panel and display lens - be VERY careful not to touch these with your soldering iron!

Page 23 Before you do ANY soldering, we remind you again to do the following: Check and organize your kit parts in whatever way Is most convenient for you. Go through this entire manual:
