Motor Braking Training System | Hands-On Electric Motor Skills

Learning System: 85-MT5A

Amatrol’s Motor Braking Learning System (85-MT5A) adds to the Electric Motor Control Learning System (85-MT5) to expand a learner’s knowledge of the common electric motor braking methods found in industrial, commercial, and residential applications. Braking is essential to motor control when motors must be stopped and restarted multiple times. Common applications include rolling mills, conveyors, and power fans. Learners study industry-relevant skills for three of the most common braking methods: electromagnetic braking, plugging, and DC injection braking. Troubleshooting braking problems under realistic conditions allows learners to experience the challenge and reward that result from applied problem solving.

The motor braking training system includes a DC braking station with power supply, transformer and bridge rectifier mounted to a slide-in panel, inertial load module with flywheel, electromagnetic brake, plugging/anti-plugging switch, student curriculum, and instructor’s guide. This system uses industrial quality components that stand up to frequent use and enable learners to better prepare for what they will encounter on the job.

Learning Topics

  • Drum Switch Plugging
  • Manual Motor Control Plugging
  • Timer-Controlled Plugging
  • Electromagnetic Brakes
  • DC Injection Braking
  • Dynamic Braking

Practice Real-World Skills on Heavy-Duty Components

Plugging, stopping an electric motor by reversing its magnetic field, is a relatively simple concept with complex and dramatic results. Amatrol’s motor braking training system covers three types of plugging: drum switch, push-button, and timer-controlled. This low cost, quick method has emergency application but does create significant stress and frequently does not bring the motor to a perfect stands still.

Extensive Braking Knowledge for Real-World Troubleshooting

Two other kinds of braking methods covered by this industrial motor control training system are electromagnetic braking and DC braking. Learners will study about the inner-workings of electromagnetic brakes, how to operate them, how the output from a DC braking station can be used to control them, and the advantages and disadvantages of using them.

Learners then apply this knowledge by connecting and operating a motor braking circuit using an electromagnetic brake and a three phase induction motor. They will then connect and operate a motor braking circuit using DC injection braking. The included components are heavy-duty and industrial quality ready for repeated use. The DC braking station includes a DC power source, control relay, and step-down transformer.

The motor braking system also covers motor braking troubleshooting by allowing learners to practice troubleshooting faults in an electrical motor control plugging circuit and a DC injection braking control circuit.

Interactive Motor Braking eLearning Curriculum

Amatrol's motor braking training system features interactive eLearning curriculum that integrates various types of learning methods to create an engaging, effective learning experience. Amatrol’s multimedia eLearning curriculum includes text with voiceovers, videos, 3D animations, pictures, and interactive activities, quizzes, and self-reviews. Specific motor braking topics covered include: drum switch plugging; pushbutton and timer plugging; electromagnetic braking; and DC injection and dynamic braking. Within these topics, learners will study objectives like connecting and operating a motor plugging circuit using a drum switch; troubleshooting a manual motor control plugging circuit; connecting and operating a motor braking circuit using an electromagnetic brake; and troubleshooting a DC injection braking control circuit.

Free Learning Management System (LMS)

Amatrol eLearning is easy-to-use for both students and instructors. Its web-based interface is simple to navigate and available on any WebGL-compatible Internet browser. Instructors love Amatrol eLearning for its simple, yet sophisticated Learning Management System (LMS). The LMS allows instructors to create custom courses, monitor student participation, track course progress, assess knowledge levels prior to a course, and test knowledge levels after completion. Learners appreciate the fact that they can start and stop as needed, moving through each Amatrol course at their own pace. If a self-review reveals that they didn’t understand a particular topic as well as they thought they did, they can revisit it before moving on.

Expand Your Electric Motor Control Training | 85-MT5 Expansion Systems

Amatrol's Electric Motor Control Learning System provides a solid foundation to build upon by adding a variety of optional expansion systems to teach additional skills related to

motor braking, reduced voltage starting, VFDs, electronic sensors & counters, and fault troubleshooting. All of these expansion systems include Amatrol's interactive eLearning.
