Variable Frequency Drive Panel Components

A. Power Supply The on-board power supply converts the 120VAC power to a manageable and safe voltage to allow the students to wire, troubleshoot, and even short circuit the control circuits with out dangerous risks. The panel operates below the NFPA 50 volt level to dispel the need to wear PPE when training.

B. Indicator Lamps While simple in construction, students will learn the importance of these devices by wiring them into common circuits, seeing them operate and troubleshooting the circuits based on their functions.

C. Variable Frequency Drive Unit Programmable electrical device that controls the rotational speed of the electric motor.

D. Ice Cube Relays Controls Relays Controls relays, often called “Ice Cube” relays due to their appearance similar to an actual ice cube are a staple in most machine controls systems. Our curriculum teaches the types, functions, and operation of these common devices, along with the common failures, and the easy methods to troubleshoot them.

E. Connection Strip The curriculum teaches a student how to correctly wire a control circuit using the same barrier strips found in most industrial machinery . This aids in teaching proper construction as well as troubleshooting methods.

F. Rheostat A resistor that is adjustable – this is the part of the VFD panel that allows for the adjustment of current or the varying of resistance to the electric motor.

G. Stop Start Station By far these industrial electrical switches are a staple in machines and process controls. The curriculum teaches all about these common devices by using real world scenarios to challenge the students throughout the training.

H. Selector Switch Selector switches are another very common control panel device that is used in many ways in common machine and process controls. Students will learn to understand, connect and troubleshoot this switch in this real world training.

I. Transducer Real world devices such as signaling and sound generators are used throughout industry. This real sound transducer adds the sound dimension to the training circuits that call be both fun and educational at the same time.

J. Electric Motor A device used to convert electrical power into mechanical power. Electric motors operate through interacting magnetic fields and current carrying conductors  to generate force, although electrostatic motors use electrostatic forces.
