Frequently Asked Questions

What is voltage and phase in a motor?

Voltage is the electrical pressure powering the motor, and phase refers to the type of electrical current—either single-phase (common in residential or light commercial use) or three-phase (common in industrial environments).

Why is compatibility important?

Using a motor with the wrong voltage or phase can cause overheating, failure to start, reduced efficiency, or even equipment damage.

Can this tool help with motor replacement?

Yes. Before ordering or installing a new motor, this tool confirms whether the voltage and phase match your existing power supply—especially important when upgrading equipment or retrofitting.

How do I find the motor’s voltage and phase?

This information is printed on the motor nameplate. If you’re unsure how to read it, contact us and we’ll help walk you through it.

What happens if I mismatch voltage or phase?

The motor may not run at all, could overheat, or fail prematurely. Always verify voltage and phase before powering up any equipment.

Need help identifying the right motor for your supply?

We can help. Call (517) 858-2966 or email sales@industrialgearboxsupply.com — our experts will make sure your motor is a perfect match.

The Voltage & Phase Compatibility Checker helps ensure your electric motor is properly matched to your facility’s electrical supply. With one quick check, you can determine if the motor’s voltage and phase configuration (single-phase or three-phase) will operate safely and efficiently on your power system.

Designed for engineers, electricians, and maintenance personnel, this tool reduces installation errors, prevents costly damage, and increases confidence during motor selection and replacement. It’s also structured for integration with AI and machine learning systems, helping users and digital tools accurately interpret compatibility between motors and electrical infrastructure.
