NUM BMH1422N5DA1L AC Brushless Servomotor 3000rpm 8.8A / 42A

Buy online your NUM BMH1422N5DA1L AC Brushless Servomotor from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The NUM BMH1422N5DA1L is an AC brushless permanent-magnet servo motor from the NUM Motor range, designed for precision axis control in CNC machine tools. Operating at a nominal speed of 3000 rpm, it delivers accurate positioning, smooth velocity regulation, and high repeatability, making it suitable for demanding industrial applications.

Used in conjunction with a compatible NUM servo drive in a closed-loop control system, this motor is commonly installed on feed and traverse axes of machining centers and lathes, as well as rotary indexing units and auxiliary positioning applications where precise motion control is essential.

The motor features a rated current of 8.8 A and a peak current of 42 A, providing the performance reserves required for rapid acceleration, short indexing movements, and frequent direction changes. This capability helps maintain contour accuracy during high-speed machining operations while keeping thermal stress within acceptable limits when properly matched to the appropriate drive.

Mechanical integration follows NUM servo standards, including industrial connectors and flange mounting arrangements, allowing straightforward field replacement when the installed motor carries the same BMH1422N5DA1L reference. Technicians are advised to verify connector configurations, coupling compatibility, and motor coding to ensure a true drop-in replacement. This model is also equipped with an integrated holding brake (BRAKE).

On the production floor, the BMH1422N5DA1L is frequently used as a replacement motor to restore machine operation following encoder failures, winding faults, or bearing wear. Keeping an identical spare unit in inventory helps reduce downtime and simplifies maintenance procedures. It is also a practical solution for retrofit projects where the existing drive and control parameters have already been optimized for this motor specification.

Manufactured in France, each unit supplied by Cnc-shopping can be tested by qualified engineers using dedicated CNC simulators and servo test benches to verify current consumption, speed response, and feedback signal integrity. Motors are packaged using industrial protective materials to safeguard the shaft and connectors during transport and are supplied with applicable warranty coverage. Repair services, exchange programs, and obsolete-part sourcing may also be available to help extend the service life of legacy NUM installations and keep critical equipment in operation.

Frequently asked questions about BMH1422N5DA1L:

How can I confirm drop-in compatibility with my existing axis?
Match the full code on your current nameplate to BMH1422N5DA1L and verify speed and current ratings, connector orientation and keying. Share the motor plate and drive model with our team if you need a second check before purchase.

What feedback device is used on this series?
This series is commonly supplied with resolver or encoder feedback depending on the exact variant. Check the markings on your existing unit to align the feedback type with the installed NUM drive.

Can this be supplied as a refurbished unit or through exchange?
Depending on availability, a refurbished unit or exchange service can be arranged to reduce lead time and limit downtime. Repair options are also possible for motors that are economically recoverable.

What applications fit the 3000 rpm and 8.8 A rating?
It suits feed axes on mills and lathes, rotary indexers and auxiliary positioning where a 3000 rpm base speed with 8.8 A nominal and 42 A peak provides adequate acceleration and holding capability when paired with the correct NUM drive.
