Learn Essential Motor Control Skills with DAC Worldwide’s Hands-On Training Systems
Industrial machinery requires a wide variety of different types of motors to function efficiently and effectively. Whether they’re powering a compressor, pump, fan, or conveyor, three-phase induction motors keep operations at industrial facilities moving steadily.
Many induction motors require significant power given their heavy-duty applications. Moreover, they draw a high electrical current upon start-up. In fact, start-up current can sometimes be as much as 5-6 times what they draw at normal operating speed. This is why they require a special device called a motor starter.
If industrial motors relied solely on circuit breakers or fuses, those would trip or blow every time the motor started. That’s obviously unacceptable in an industrial setting. Instead, specialty motor starters start and stop induction motors using manual or automatic switches. They also protect motor circuits from excessive heat caused by overloads during normal operations.
Motor starters consist of two primary parts: (1) an electromagnetically operated set of contacts (called a contactor) starts and stops the motor by beginning or ending the flow of electrical current; and (2) an overload relay that protects the motor from drawing too much current and overheating.
Likewise, motor starters usually consist of two circuits: (1) a power circuit that transmits the primary voltage to the motor via the starter contacts and overload relay; and (2) a control circuit that manages the contactor coil that creates the electromagnetic field that operates the power contacts.
Because there are so many different types of industrial applications that require induction motors, there are likewise a wide variety of different types of motor starters. One common type is the reversing magnetic motor starter. Reversing starters, as their name implies, are specifically designed to efficiently reverse shaft rotation of a three-phase induction motor.
Reversing starters work by interchanging two contactors supplying electrical current to the motor, as well as having both a forward and a reverse starter. To ensure that only one of the starters can be engaged at any particular time, reversing starters feature both mechanical and electrical interlocks for enhanced safety.
Industrial maintenance technicians must be familiar with all sorts of induction motors and their motor starters. Hands-on training in electrical maintenance can elevate your technicians’ skills to the next level.
For example, if you want to ensure your maintenance technicians have the skills to work with reversing magnetic motor starters, DAC Worldwide’s 3-Phase Motor Control Training System with Magnetic Starter (423-000) offers comprehensive training in the operational principles, wiring, fault troubleshooting, and application of industrial three-phase, reversing magnetic motor starters.
The 3-Phase Motor Control Training System with Magnetic Starter is self-contained, allowing for individual study by a single student or a small student group. While often used independently, the training aid can be integrated with other optional products relating to programmable controllers, pilot devices, and motor-driven mechanical systems.
This electrical trainer includes a variety of industry-standard components, including: a three-phase induction motor; reversing magnetic motor starter with auxiliary contacts, mechanical and electrical interlocks, and overload relay; on-board wiring devices including Hand-Off-Auto (HOA) control station, manual control station, and automatic timer; color-coded, shielded banana-jack receptacles for all motor leads, supply connections, and control components; circuit breaker with lock-out/tag-out; keyed power switch; pilot light and emergency stop switch; and four instructor fault switches to create common component faults for troubleshooting instruction.
The 3-Phase Motor Control Training System with Magnetic Starter is only one of DAC Worldwide’s many electrical training systems.

Fundamental Electrical Skills Training: Powering the Path to Success
No matter their experience, skill level, or desired specialty, all individuals aspiring to become electrical professionals need the same fundamental electrical skills. These include understanding the basic principles of electricity and working with common electrical components, such as wiring, motors, and circuits. By mastering core skills like these, learners can help ensure they work safely and efficiently in whatever specified path they choose, whether that is industrial, commercial, or residential electrical careers.
As with any discipline, learning fundamental skills establishes a foundation from which a learner can build more complex concepts and skills. An electrician who now wires entire buildings for manufacturing processes was once a student learning about electric current. Furthermore, that same electrician could choose to expand their skills into more advanced or niche areas, such as performing industrial maintenance for the robotic arms they run power to, which would require that they rely on their understanding of basic PLC operation to progress to the complex coding needed to ensure manufacturing level precision.
Additionally, an electrical technician’s understanding of basic concepts and their abilities helps build confidence that translates to efficiency. For example, an HVAC technician is able to quickly restore air conditioning to a home because they understand how the circuit board, fan motor, compressor, and other components work both individually and together to create a working system. However, if the technician did not have a knowledge of wiring practices, the job would move much more slowly and, if done wrong, could even be dangerous.
In the same vein, industrial workers that know the do’s and don’ts of electrical practices can help recognize and prevent risky electrical setups. This makes a workplace safer for everyone and can help a company avoid downtime. In essence, fundamental electrical skills help prepare future technicians of many career paths to handle any job they will face in the field and provide the first step in pursuing a successful career in the electrical field.
DAC Worldwide’s Electrical Training Systems
DAC Worldwide offers many training systems that teach learners the fundamental electrical skills they need for a successful career.
