전기 공학 Jobs

Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.

    We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting certain options...

    I have a mechanism that can manufacture the rotors for the generator . I need the coils and the capacitor designed so the rotors rotate and collect the dc power renerated by the coils in multi capacitors . Then through the switch design this is released into the batteries as a charge . As one capicitor is discoraging another is charging . As there will be multi coils there must be multi capacitors to keep this process rotating . And it must be design for safety as there will be a lot of power being renerated and stored for release . This must be able to charge a 48v or 52v battery ok . Can you design if not i will put this back here to get others to design . But either way you must work with them to design capacitors and system to have the battery switch also switch output of capacitors in...

    Generate new code for an ARM series MCU (likely the ATSAME70J19B). Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

    This report introduces the wireless sensor interface project of the SEP group project. The objective of the project is to develop a system to collect data from sensors, and to transmit this data wirelessly to a node which passes the data to a PC. Wireless transmission methods have been investigated, and it was decided that a proprietary protocol would be designed. A TDMA based protocol has been designed. Sensor tests have been performed, and the protocol has been designed and detailed in this report. This report also discusses the progress made to date on the project, and proposes a timeline for the completion of the projects

    Main idea. To have multiple buttons around a office/home and when someone presses it a blink/signal will occur on the units like a common signal for an event. To ACK the signal everyone will need to press the button to confirm. This is a MVP concept design and I will add more functionality later. The only HMI will be a button and a LED (maybe RGB) so all info will be via that interface I will do all HW myself and want a fully functional software delivered. Assume the freelancer have this stuff at home to laborate and test the HW setup for a secure and proper debugging.
