Wire Motor Control Circuits in Your Browser
Wire motor control circuits. Test them with a multimeter. Break them and find out why.
Free, no account needed
Each trainer guides you through a complete industrial control circuit:
Complete the Learn Phase — An animated guided lesson walks you through how the circuit functions and familiarizes you with the concepts to successfully complete the circuit in the build phase.
Wire the Circuit — Click terminals to make connections using what was demonstrated in the learn phase. A progress checklist tracks each section as you go.
Go Further — Troubleshoot injected faults with the multimeter and try alternate wiring methods in the exploration sections.
Prove Your Understanding — A final test checks that you understand the circuit, not just that you followed the steps.
Circuit Categories
Start free with the Basic Motor Starter — no account needed. Pro unlocks all five trainers at $15/month or $129/year.
Motor Starters
Free, no accountStart 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 how each one combines momentary operation with run/stop, then explore pilot light indication and two-location circuits.
Reversing Circuits
Dual-contactor reversing with electrical interlocking. Wire the load-side phase swap, understand why interlocks matter, and diagnose faults across both forward and reverse paths.

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.

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.
Who Uses Electrimancer
Electricians moving into motor controls work. Maintenance technicians stepping 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.
Available Circuit Trainers
- 3-wire start/stop motor starter with fault diagnosis — troubleshoot stuck contacts, broken seal-in paths, and tripped overloads
- Control transformer starter with NEC 430.72(C) fuse sizing — calculate and install primary and secondary overcurrent protection
- Control relay jogging circuit with two explorations that show when the control relay is and isn't needed — rewire for two-location start/stop and for jog-only to see what changes
- Selector switch jog circuit with pilot light exploration — wire NO and NC auxiliary contacts for motor status indication
- Reversing hoist starter with two bare contactors, a standalone overload relay, electrical and mechanical interlocking, and a 24V control transformer — diagnose faults across forward and reverse paths
