The Ametek Lamb 116036-13, listed here as 11603613, is a 5.7-inch two-stage quiet bypass motor with peripheral discharge, wound for 220 to 240 volt equipment. Two details make it worth knowing. The first is the bypass construction: the working air is routed away from the windings and the motor is cooled by a separate air path, which is what allows it to be used in wet and dry recovery machines. The second is the -13 suffix, which on Ametek Lamb motors indicates a small additional fan below the lower ball bearing that blows debris away from that bearing. That is a service-life feature, and it matters most in the dusty applications these motors usually land in.
Use Cases
- Rebuilds 220-240 volt central vacuum power units using a 5.7-inch two-stage motor
- Restores commercial canister and recovery vacuums on 240 volt single-phase supply
- Replaces motors in dusty environments where lower bearing contamination shortens motor life
- Powers material handling and transfer equipment that needs bypass cooling
- Serves as a quieter replacement where a quiet bypass peripheral motor is specified

Fits
No manufacturer machine compatibility list was located for this exact part number. The 5.7-inch two-stage peripheral bypass format on 240 volts is used across several equipment brands, so verify by measurement: body diameter, stage count, voltage, discharge style and mounting arrangement all have to match the motor you are removing. Sealed lift and current draw figures for this suffix were not found in a source reliable enough to publish, and are therefore not stated above. Contact us before ordering if either figure is critical to your build.
Frequently asked questions
What does the -13 on the end of the part number mean?
On Ametek Lamb motors that suffix indicates a small additional fan fitted below the lower ball bearing, which blows dirt away from that bearing while the motor runs. It is a durability feature aimed at dusty applications, where contamination of the lower bearing is a common cause of early motor failure.
What makes it a quiet bypass motor?
Quiet bypass is Ametek Lamb's designation for a bypass motor built with additional attention to noise, typically through the fan and discharge design. It is the same basic construction as any bypass motor, with the working air kept off the windings and a separate cooling path for the motor itself.
Can I run it on 120 volts?
No. It is wound for 220 to 240 volt operation and will not develop useful suction on 120 volts. Machines on North American household power need a 120-volt motor of the same body size and configuration instead.
Why are the sealed lift and amperage figures missing?
Because no source reliable enough to quote was found for this exact suffix. Publishing a figure lifted from a similar part number would be worse than leaving it out, since motor selection often turns on exactly those numbers. Contact us and we will try to confirm them before you order.
Discount Cleaning Products is an authorized dealer for Ametek Lamb vacuum motors and stocks replacement motors, carbon brushes and service parts for commercial and central vacuum equipment. Orders are supported by a US-based team that works with these motors every day, so if you are unsure which body diameter, stage count, discharge style or voltage your machine takes, ask before you order.
