Wire Motor Control Circuits in Your Browser
Interactive circuit trainers with accurate voltage simulation, a built-in multimeter, and an AI mentor.
Each trainer guides you through a complete industrial control circuit:
Wire the Circuit — Connect terminals on accurate component models including contactors, overload relays, control stations, and 3-phase motors. A progress checklist verifies your work as you test the circuit.
Test with the Multimeter — Measure voltage, verify continuity, and confirm correct operation at every stage using the built-in digital multimeter.
Go Further — Depending on the circuit, troubleshoot injected faults, explore alternative wiring methods, or consult the AI mentor with questions about your circuit.
Prove Your Understanding — Pass a final comprehension test that verifies conceptual knowledge, not just correct wiring.
Learn the Circuit Before You Build It
Every trainer starts with an animated lesson that walks you through the circuit — what each component does, how wires carry current, and why the design works. Watch the circuit build itself wire by wire, see what happens when things go wrong, and operate the finished circuit before you touch a single terminal. When you start wiring, you already understand what you're building.
Live Ladder Diagram
A real-time schematic builds as you wire and updates as the circuit operates. Watch rungs energize and de-energize as you press buttons and toggle switches.
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.
Interior and Exterior Component Views
Click any component to open its enclosure and inspect internal contacts, coil windings, and terminal arrangements. See why contacts move together and how overload relays work.
Go Beyond the Main Circuit
After mastering the base circuit, explore alternative wiring exercises — such as adding pilot lights for motor status indication, rewire for jog-only operation, or try two-location control.
AI 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. It's not a chatbot with canned responses — it reasons about your specific circuit.
Circuit Categories
Explore different types of motor control circuits, from basic start/stop to advanced reversing operations.
Motor Starters
Wire 3-phase motor starters with seal-in contacts, overload protection, and control transformers. Diagnose simulated faults and size fuses per NEC code.
Jogging Circuits
Compare control relay and selector switch jog methods. Explore alternative wiring configurations and add pilot light indication.
Reversing Circuits
Forward-reverse motor control with electrical interlocking and phase swapping. Wire dual-contactor circuits for hoists and conveyors with 24V control transformers. Includes fault diagnosis with simulated failures and comprehension tests.
Built for Electrical Professionals
Electrimancer is an online motor control circuit simulator designed for electrician apprentices, trade school students, industrial maintenance technicians, and engineers. Each circuit trainer replicates a real industrial configuration using NEC-standard components — contactors, overload relays, control transformers, control stations, selector switches, and 3-phase motors — with accurate voltage propagation and contact behavior.
Interactive Simulation, Not Static Diagrams
Unlike ladder diagrams in a textbook, these trainers let you drag wires between terminals, operate pushbuttons and selector switches, and measure voltages with a built-in digital multimeter. Circuits respond to your wiring in real time — if a connection is incorrect, the circuit behaves accordingly. Every trainer includes guided wiring, multimeter verification, and a final comprehension test. Trainers also include fault diagnosis or alternative wiring explorations that build on the concepts presented in each module.
