Motor Control Jobs

I have two BLDC motors running on VESC-based controllers and I need them responding smoothly to a radio-frequency hand-held remote. The goal is true “tank style” drive: forward, reverse, pivot left or right, plus proportional speed and braking on each trigger. Here is what I still need done: • Bind and map the RF receiver to both VESCs so every channel on the remote translates cleanly to speed, braking and direction. • Set safe current limits, regenerative and active braking parameters, and be sure neither motor over-currents under stall conditions. • Calibrate RPM and refine torque curves so the response is even across the whole throttle range. • Synchronise the two controllers over CAN so they act like one power-train without cogging or desync a...

Control VESC-based motor control system, including BLDC motor setup, remote control integration, motor tuning, current limiting, braking configuration

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...

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 ...

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, ...
