The speed range of a dental electric micromotor is typically 1,000-40,000 rpm compared to the 5,000-25,000 rpm of conventional air motors. Crucially, with an electric micromotor you have 100% of the torque available throughout the whole speed range, and when applying pressure.

These characteristics make the electric micromotor perfectly suited to run with so-called 'speed increasing contra-angles', allowing friction-grip bur speeds of up to 200,000 rpm. Importantly, the speed increasing contra-angle is equipped with quadruple spray.

However, electric micromotors typically come built into the dental unit, and many practitioners do not have this set-up. For this reason, there are simple and effective solutions available allowing existing dental units to be converted to electric motors, without the requirement of having to call out an engineer.

One such solution is the cost-effective BA EM420 'plug & play' motor which allows the existing air motor outlet to be converted to electric. Once the EM420 is plugged in, the in-built spray can be switched on, speeds can be programmed between 1,000 and 40,000 rpm and the efficiencies of the red banded speed increasing contra-angle can be fully taken advantage of.
