When it comes to vacuum motors, one name stands out: Ametek Lamb. Renowned for their quality and durability, these peripheral and tangential bypass motors are used across the world in a variety of applications, especially central vacuums and blowers. In this guide, we will explore the different models and their features and show you how to find the motor number of your unit.

Please Note: The motor number is essential when ordering replacements or parts. Always jot it down and keep it somewhere safe for easy reference.

How to Identify Your Ametek Motor Number

The most important thing you need to know.

The motor number, usually located on the motor’s label or engraved onto its surface, is a crucial string of numbers that provides important information about the motor. It typically specifies the motor’s model and the specifications pertaining to its operation. If you’re having trouble locating the motor number, don’t despair! It’s usually found on a sticker or a metal plate on the motor’s case. You might need a flashlight if it’s located in a hard-to-see area.

Step 1: Locate the Motor Label — This is typically found on the side or bottom of the motor. It may be a sticker, a metal plate, or printed directly on the casing.

Step 2: Find the Motor Number — The motor number is typically a sequence of digits, such as “116125–01”. It will be listed on the label along with other specifications.

Step 3: Note Down the Number — Write down the number or take a photo for your records. This will be useful for maintenance, replacements, and troubleshooting.

Explanation of Features and Specifications

All Ametek Lamb motors share some common features, such as being two-stage motors and having a 5.7"/145mm diameter. However, there are also unique characteristics for each model.

Voltage

The voltage of a vacuum motor refers to the electrical power required for it to function. Models range from 24 volts 36 volts, and as high as 240 volts.

Bearing Type

Ball bearings are used in all models to minimize friction and facilitate smooth operation. Some models (like the 116336–01) feature double ball bearings, enhancing durability and stability.

Speed

All models are single-speed, providing consistent performance across all operations.

Discharge Type

Most models feature a peripheral bypass discharge. Some models feature an ACUSTEK® low-noise peripheral bypass discharge, making them a quieter option.

Bracket Material

The end bracket of these motors is made from thermoset plastic, providing a robust and heat-resistant construction. Some models also feature an aluminum commutator bracket for added sturdiness.

Whether you’re seeking a motor for a new vacuum system or replacing the motor in an older unit, understanding these features will help you choose the right Ametek Lamb motor for your needs.
