What is a brushless electric motor and what benefits does it offer me as a user?

The brushless electric motor is considerably less susceptible to wear than a brush motor, which in turn translates to minimised service and maintenance work. This also means less downtime for the user when servicing proves necessary.

Does the electric motor need to be lubricated with oil?

No, the motor bearings require no maintenance. Any additional oil service would reduce the service life of the bearings.

Should I always call my W&H service partner in advance before sending devices/instruments in for repair?

If you are not completely sure of the cause of the problem, it is better to contact your W&H service partner first and speak to a technician. It is sometimes possible to resolve malfunctions together with the technician and decide what needs to be sent in for repair.

Does the Add-on version of the EM-12 L electric motor require maintenance?

The EM-12 L electric motor as an Add-on version including accessories requires a regular check once every three years unless shorter intervals are prescribed by law. The regular service must only be performed by an authorised W&H service partner. More detailed information on this topic can be found in the “Service” section of the instructions for use.

Does the Built-in version of the EM-12 L electric motor require maintenance?

The Built-in electronic component does not require separate maintenance. However, regular servicing together with the rest of the dental unit should be performed at the intervals prescribed by the pertinent legislation. This makes it possible to guarantee proper function and safety. More detailed information on this topic can be found in the “Service” section of the respective instructions for use.

How can I integrate the EM-12 L electric motor into my unit as a Built-in version?

The EM-12 L electric motor can be integrated into a dental unit by selected dental unit manufacturers or their service technicians.

How do I connect the EM-12 L electric motor to my unit as an Add-on?

To connect the EM-12 L electric motor to your dental unit as an Add-on you require a free turbine hose on your dental unit and the possibility of connecting the control to the mains via the included power supply unit. You can control the EM-12 L electric motor using the foot control of your dental unit.

Can I sterilize my EM-12 L electric motor in a sterilizer?

Yes, if your EM-12 L electric motor features the symbol “Sterilizable up to the stated temperature”.

Which contra-angle handpiece series is recommended for the EM-12 L electric motor?

The W&H Synea series – the glass rod elements are optimally suited for use together with the EM-12 L motor and its integrated LED+.

EXPERT TIP

“An electric motor with high-speed contra-angle handpieces is the best choice for the preparation of CAD/CAM treatments”

Polieren, Prophylaxe

composite, ceramik, metal, universal

Crown and cavity preparations
Removal of crowns and bridges

Excavating

Removal of fillings

Remove fillings safely and efficiently.

Finieren

Reach the required speeds of the files.
Profile the preparation surface more minimally invasively. Finish the preparation margins with even more control.

“The most important benefits that I can comment on from my own experience are the following: Control of the preparation, precise, neat and uniform margins that are easy to scan. Less vibration compared with turbine handpieces, thus less fatigue and force required during the preparation procedure. ”
