  • Multi Interface USB Adapter

    SUB-20 - Dimax

    SUB-20 is a versatile and efficient bridge device providing simple interconnect between PC (USB host) and different HW devices and systems via popular interfaces such as I2C, SPI, MDIO, RS232, RS485, SMBus, ModBus, IR and others. It is also a full "any to any" converter between all supported interfaces and I/O features. SUB-20 is a powerful I/O controller with 32 GPIO, 8 Analog Inputs, PWM Outputs, Edge DEtectors, LCD, Leds and push buttons.SUB-20 system includes SW package containing driver, API Library, GUI and Command Line based applications, C,C++,C#,VB.net, MATLAB, LabView sample code and documentation. SUB-20 can be used with PC 64/32 bit running Windows 2000/XP/Vista/Win7/Win8, MacOS, Unix/Linux and DOS.Working with SUB-20 does not require deep knowledge of low layers of the specific interface. All you need to do is to call right API function at the right place. And this is really very easy as API functions are well documented and "exampled". API set is relatively small but comprehensive.SUB-20 is equipped with status Leds, optional LCD and buttons. All this guarantee fast and comfortable development, field debugging and maintenance of applications including option of standalone operation.

  • Motor Test for Electric Scooters

    MOTOMEA

    *The performance data of electric motors, in the majority of all cases, is performed by a brake test. Power input is calculated from current and voltage. Torque and power output are measured with a brake. It is important to reach, for each point, a persistent temperature. In case of large outer rotor BLDC motors, which are usually used for electric scooters, this traditional procedure may take many hours to complete, and is very complicated. *For several years, an innovative motor tester of MEA Testing Systems Ltd. is on the market. This testing system avoids any temperature confusion by testing a motor at constant temperature over the entire speed range. The test procedure is very fast, and gives the full load performances, including PWM current, voltage, torque, and driver efficiency, from stall up to no load. *During the test procedure, the motor is freely accelerated from stall to no load speed. The load of the motor is only the predetermined inertia of the rotor. From the moment of inertia and the acceleration, the torque of the motor is calculated and, also, the power output over the whole speed is given. Since the entire measuring time, depending on the motor size, is usually less than one second, the motor has no time to warm up. It remains at room temperature.
