Wire Motor Control Circuits in Your Browser
Wire motor control circuits. Test them with a multimeter. Break them and find out why.
Each trainer guides you through a complete industrial control circuit:
Wire the Circuit — Click terminals to make connections. A progress checklist tracks each section as you go.
Test with the Multimeter — Measure voltage and check continuity at every stage, just like you would on a panel.
Go Further — Troubleshoot injected faults, try alternate wiring methods, or ask the mentor what went wrong.
Prove Your Understanding — A final test checks that you understand the circuit, not just that you followed the steps.
Learn the Circuit Before You Build It
Watch the circuit build itself wire by wire — see what each component does, how the current flows, and what happens when things go wrong. When you start wiring, you already know what you're building.
Go Beyond the Main Circuit
Once you've wired the base circuit, try variations — add pilot lights for motor status indication, rewire for jog-only operation, or set up two-location control.
Built-In Mentor That Reads Your Circuit
Ask it why your contactor won't pull in — it reads your actual wiring and tells you what's wrong. It knows both NEMA and IEC conventions, won't penalize valid alternate approaches, and guides you from symptom to root cause instead of handing you the answer.
Find the Fault
Each trainer includes fault diagnosis scenarios — a technician reports a symptom, and you use the multimeter to find the failed component. Stuck contacts, broken seal-in paths, open coils.
Wire It Wrong, It Will Arc When Energized
Short circuits trigger an arc flash overlay and automatic power trip. The simulation has real consequences — land two phases on the same conductor and find out.
Circuit Categories
Five circuit trainers across three categories, with more in development.
Motor Starters
Start here. Wire a 3-wire start/stop circuit, then move to a control transformer with NEC fuse sizing. Fault diagnosis and troubleshooting included.
Jogging Circuits
Two ways to jog a motor — a DPDT control relay and a selector switch. Learn why one is safer, then explore pilot light indication and two-location circuits.
Reversing Circuits
Dual-contactor reversing with electrical interlocking. Wire the phase swap, understand why interlocks matter, and diagnose faults across both forward and reverse paths.
Who Uses Electrimancer
Electrician apprentices preparing for motor controls coursework. Maintenance technicians moving into controls roles. Engineers who can read a ladder diagram but haven't landed wires on a contactor. Trade school instructors looking for a practice tool that doesn't require a physical training panel. If you need to understand how motor control circuits work — not just on paper, but in practice — this is built for you.
