Control de Motores Jobs

I need a senior-level electrical engineer who can split time between working remotely and being on site in Orange County, CA. The project centers on motor-control electronics, so every board you design must reliably drive, sense, and protect a variety of motors under real-world loads. Here’s the flow I expect: • Draw the schematic and capture the BOM for a new motor-control PCB, selecting components that meet cost, thermal, and EMI constraints. • Lay out the board for manufacturability, noise immunity, and serviceability, then generate all fabrication and assembly files. • Oversee prototype builds, bring the hardware up in the lab, and run functional, thermal, and load tests with my existing motor rigs. • When issues surface, dive into trace analysis, osci...

Saya sedang mengembangkan mainan pesawat bertenaga solar cell (2 V DC / 55 mA) dan memerlukan referensi micro motor DC ber-stall current rendah yang benar-benar bisa berputar dengan pasokan sekecil itu. Detail kebutuhan: • torsi & kecepatan tidak penting—yang utama motor mau start dan berputar stabil. • Motor DC harus kompatibel dengan ukuran solar cell yang sudah saya miliki. • Ya, harus sangat kecil; diameter dan panjang total tidak boleh melebihi motor bawaan di lampiran. Yang saya harapkan Anda kirim: 1. Daftar minimal 5 kandidat micro motor DC dari Alibaba atau marketplace global lain (AliExpress, Mouser, Digi-Key, dsb.). 2. Untuk tiap kandidat: link langsung ke produk, datasheet atau lembar spesifikasi, tegangan kerja, arus no-load dan stall, ...

I need a compact, reliable AC solid-state relay designed specifically for driving pump loads. The control side will accept 3–32 V DC, while the load side must safely switch 24–380 V AC at a continuous 25 A. Core expectations • Status indication via a front-panel LED • Full opto-isolation between control and load • Zero-cross switching is preferred to minimise inrush, but I will consider a non-zero-cross solution if it offers clear advantages for motor-driven pumps. • The housing should be compatible with a standard heat-sink footprint, and I am open to either DIN-rail or panel mounting depending on what your thermal calculations show to be most practical. Deliverables 1. Full schematic with component values and reference designators 2. PCB ...

Looking for an experienced Python/Embedded developer to adapt an existing Raspberry Pi pressure-control project for a Nano-based board. Current application: - Reads air pressure from a sensor - Turns a motor on when pressure falls below threshold - Runs hourly checks - Existing code is approximately 75-90% complete Requirements: - Refactor and finalize the code for Nano hardware - Configure GPIO, sensors, motor, and indicators - Enable automatic startup after boot or power loss - Create a Windows batch deployment script - Provide setup documentation and pin mapping - Verify reliable operation through power-cycle testing Deliverables: - Updated Python source code - Windows deployment script - README documentation - Power-cycle test confirmation

I need a proven method to bring the traveling and hoisting drives of an EOT crane into perfect electrical synchrony so that both ends move at identical speeds under every load condition. The core objective is speed-matching; everything else—position alignment or load sharing—follows once the motors stay locked together without hunting or drift. Please outline, in a detailed project proposal, how you would: • Sense real-time motor speed (encoder, tachogenerator, or another reliable feedback device). • Close the loop through the existing VFD/PLC or recommend a replacement architecture if required. • Handle calibration, fault detection, and re-synchronization after an emergency stop. • Supply wiring diagrams, parameter tables, and the logic code (Siemen...
