Three-phase motor control can look wonderfully tidy on a schematic. Put the same circuit in front of a beginner, with contactors, overload terminals, auxiliary contacts and several nearly identical wires, and that confidence may disappear rather quickly.
The Udemy course 3 Phase Motor Control Bootcamp teaches how common motor-control circuits are designed, wired and tested using real electrical components.
I believe it is a very good practical course for apprentices, electricians and maintenance technicians who want to understand traditional motor-control wiring before moving deeper into PLC-controlled systems.

What Does the Course Cover?
Created by The Wiring Wizard, the course contains 11 sections, 90 lectures and just over four hours of video. The current Udemy listing shows a 4.7 rating from around 1,690 reviews, with more than 6,100 enrolled students.
The course focuses on seven essential three-phase motor-control circuits:
- Direct-on-line starting
- Forward and reverse control
- On-delay starting
- Off-delay control
- Star-delta starting
- Mixed-voltage control circuits
- DC injection braking
Students also learn about three-phase squirrel-cage induction motors, contactors, thermal overloads, relays, circuit protection, push buttons, indicator lamps, timers and power supplies.
Starting With the Components
Before building complete circuits, the instructor explains the individual parts.
You see how a contactor switches three-phase power, how an overload interrupts the control circuit, and why normally open and normally closed auxiliary contacts are so important.
The course also covers six-terminal motor connections and explains the difference between star and delta configurations. That foundation matters. Without it, a star-delta schematic can look like someone simply added three contactors because one was not confusing enough.
Building a DOL Starter
The direct-on-line starter is developed gradually.
Students begin with the power circuit before adding the start button, stop button, holding contact, emergency stop, overload protection and indicator lamps. The course then demonstrates how to wire and operate the finished circuit.
This step-by-step approach is probably the course’s greatest strength. Instead of presenting one finished drawing and expecting beginners to understand it, each part is added for a reason.
Reversing and Star-Delta Control
The reversing section explains how swapping two phases changes the motor’s direction. It also demonstrates electrical interlocking so the forward and reverse contactors cannot energise simultaneously.
Later, the star-delta section covers motor connections, reduced-current starting, timer-controlled switching and the interlocks needed to prevent the star and delta contactors from closing together.
That is not a situation where “let us see what happens” is a recommended troubleshooting strategy.
Timers, Mixed Voltages and Braking
The course also introduces on-delay and off-delay relays, including their use in automatic starting and stopping sequences.
Mixed-voltage examples show how a three-phase power circuit may operate alongside lower-voltage control equipment, including 24 V DC devices. The final major section covers DC injection braking and explains how direct current can be applied to stop a motor more quickly after AC power is removed.
Who Is This Course For?
The course is intended for:
- Electrical apprentices and pre-apprentices
- Industrial electricians
- Maintenance technicians
- Aspiring electrical-control technicians
- Automation students learning motor circuits
Some knowledge of AC circuits, motors, Ohm’s law and normally open or normally closed contacts will help, although the course briefly revisits the basics.
Are There Any Downsides?
The course was last updated in February 2019. The fundamental relay and motor-control principles remain useful, but equipment standards and recommended practices should always be checked against current local regulations and manufacturer documentation.
It also focuses on traditional push-button motor control rather than PLC programming, VFD commissioning or advanced industrial networks.
Final Verdict
3 Phase Motor Control Bootcamp is a very good course for learning how practical motor-control circuits are designed and wired.
Its real-component demonstrations, gradual circuit development and coverage of DOL, reversing, star-delta, timers and braking make it particularly useful for hands-on learners.
