Guided advisor service

Motor replacement support that starts with your real equipment.

LEESON Motor helps maintenance teams and OEM buyers move from a confusing nameplate to a practical stocked motor choice. The service is intentionally plain-English: we check HP, rpm, voltage, phase, frame, shaft, enclosure, rotation, brake data and capacitor notes before a recommendation is made.

For urgent MRO work, the first question is whether a safe stock replacement exists. For OEM programs, the question becomes repeatability: the same approved motor, the same wiring notes and the same purchasing record each time a machine is built or serviced.

Where our team removes uncertainty

Nameplate cross-reference

We translate faded or partial nameplates into a clear comparison of horsepower, rpm, voltage, frame, enclosure, service factor and mounting. If a detail is missing, the response tells you exactly which photo or measurement closes the gap.

Single phase wiring review

For 115 V and 230 V single phase motors, we review reversible wiring, capacitor function and terminal markings. The goal is not to guess, but to keep the installer from repeating a wiring mistake that overheats a replacement.

Brake motor substitution

Brake voltage, torque setting, manual release, rectifier style and duty cycle are checked beside the motor data. A brake motor is a system choice, so we flag items that need confirmation before the unit leaves stock.

OEM repeat order notes

When an approved alternate is used repeatedly, we create a readable note set for engineering, purchasing and maintenance. That record keeps future orders aligned with the same NEMA MG 1, UL 1004 and CSA expectations.

Embedded FAQ

Questions we answer before a quote

A photo of the nameplate plus application notes is usually enough for the first pass. If the motor is unreadable, shaft dimensions, frame measurements, voltage, phase and mounting photos help us narrow the path.

We can compare IE3 Premium Efficiency options when the duty cycle and enclosure support the change. We do not promise impossible efficiency gains; the quote explains the practical tradeoff between stock speed, power draw and fit.

Yes. Emergency requests are triaged for stocked ratings first, then for close alternates. If an alternate changes frame, shaft, voltage, enclosure or brake detail, the risk is called out before shipment.

Before guidance

Teams often start with a partial model number, a motor that failed in service, a capacitor question and a purchasing deadline. The risk is ordering a motor that physically fits but fails on rotation, duty, brake release or enclosure.

After guidance

The final recommendation includes fit assumptions, stock status, alternate notes and remaining confirmations. Mechanics know what to install, buyers know what to reorder and engineers know why the substitute is acceptable.
