Electric dental handpiece motors are an alternative to air turbine powered handpiece motors. The main benefit to an electric motor is a consistently high torque throughout rpms speeds. These electric dental handpiece motors often empower about 3 Ncm or 55 watts and depending on the handpiece, RPMs can range from 100-400,000. Many electric motors support straight and contra-angle handpieces and some vendors manufacture a system with two motors allowing switching between low-speed and high-speed without removing dental attachments. Often quieter then their air turbine counterparts, the electric dental handpiece employs high torque and boasts precision cutting with less vibration. LED lighting is often the primary light source. Electric dental handpiece motors can often be integrated into an existing touchpad or computer systems. Dental handpiece connection type is most likely “E” couple, as this is the most commonly used. When purchasing an electric dental handpiece there is an important aspect to consider; infection control. Many electric motors are not completely autoclavable; often only the micromotor housing is autoclavable not the micromotor itself. This is potentially an infection hazard and should be a concern when considering an electric dental handpiece motor.
