$ 495.00

The only dynamometer developed specifically for drone designers with a USB interface and powerful software for automated control and data-logging. The ideal tool for optimizing the performances of drones, robots and radio-controlled vehicles.

SKU: J8UD

Description

This is the Series 1580 dynamometer and thrust stand. It measures both torque and thrust. We also have the Series 1520 thrust stand, which does not measure torque.

This tool is rated for motors and propellers generating thrusts of up to 5kg. For more thrust, have a look at our upcoming Series 1780.

Series 1520 or Series 1580?

    Hi,I am interested in the 1580.I want to get some experiment data to make system identification.So, I have some questions:
    (1)what is the sample time?
    (2)can I use chirp signal or other signals?
    (3)Are the data saved at real-time?
    Thanks.

    • Hi Guijie Ren,

      1) The sample time is 8 hz for the load cells and 50 hz for the RPM and current on a fast computer.
      2) What is the chirp signal for? Using the scripting system, you can send almost any kind of signal to the motor.
      3) The data is saved in real time in a CSV file.

      Cheers,

    Thank you for your prompt reply.
    (1)The chirp signal is a multi-sine signal to use stimulate the motor system to get data. I can make FFT analysis of the data to get Bode graph;
    (2)If 50 Hz is the fastest, this means the max frequency of the signal is 25 Hz.So, I want to know what is the bandwidth of the most BLDC?
    Thanks again.

    Hi,I have some other questions:
    (1)what is the signal of Optical RPM Probe and the load cells ? Is it Voltage signal?Can I use them to connect other boards?
    (2)Can you provide the invoice?I am Chinese.
    (3)when will you deliver/ship my cargo?
    (4)Can we sign sales contract at first?
    Thank you!

    • The unit was designed for steady state optimization in flight. It is not ideal, but it is possible to do some dynamic tests. The bandwidth of BLDCs will depend on the ESC, the motor size as well as the load. The optical RPM probe receives 5V and outputs a square wave, which is function of what is in front of the sensor (white of black tape). The board will measure the frequency very precisely. You can use the servo output to control other devices. I will email you about the shipping and invoicing question. Cheers,

    I actually got a 1580 in August, but am just now getting around to setting it up. Assembly is simple. I used blue Locktite on all the screws. I am using it from a MacBook Pro. No issues at all with installing and setting up the software. Calibration was straightforward, just follow the on screen instructions.

    I had a bit of an issue when the ESC armed, and “beeped” the motor. That showed up as a high RPM on the electrical RPM sensor, and caused a “out of limit” shutdown. I just increased the RPM limit and it worked fine after that.

    My first test was a low Kv motor and the electrical RPM sensing did not work, but I just noticed in the specs that it has issues with Kv<600, and my motor was about 400. I had already bought the optical sensor, so I just have to install that before I test again.

    The automatic testing scripts are simple and work well. They are easy to modify if you know anything at all about programming in a C like language. (expect to have to do some minor edits to things like the throttle command range)

    I have not yet checked the calibration on voltage or current readings, but they seem about right.

    I have done a lot of dyno testing of small motors and small piston engines in my career and there have ALWAYS been problems of some type. The 1580 and its software just WORK, and makes testing easy and fast.

    I have only done one set of tests with it so far, so we will see how things work out in the long run, but so far, I am very impressed with the system, and I think its well worth the cost.

    • Thanks a lot for the feedback! We will continue to work on tool and software to keep improving!

      Cheers,

    Hello
    I just got my 1580 series but i need to mount it on another device. So I was wondering if there’s anywhere I could find blueprints of the dynamometer

    • Hi Juan,

      You can have a look at the datasheet of the 1520: They share the same hole pattern for the lower support part. We will update the datasheet of the 1580 to include the hole pattern too.
