PRIME 115 Professional Brushless Laboratory Micromotor

The PRIME 115 is where the high-performance tier of the brushless range begins. 210W of output is a noticeable jump from mid-range units, and the brushless setup means there’s nothing inside wearing down over time. No carbon brushes to replace, no maintenance schedule to keep track of. It runs quietly, which in a busy lab environment isn’t a small thing. For a unit that’s meant to handle heavy daily use, the long-term reliability is built into the design from the start.

Speed range runs from 1,000 to 50,000 RPM. Torque maxes out at 7.2 Ncm, which matters most when the material pushes back. Chrome-cobalt, zirconia — these aren’t forgiving materials, and a motor that bogs down mid-grind creates real problems. The PRIME 115 doesn’t have that issue. Rotation stays constant under load, so grinding and finishing through tough materials doesn’t turn into a battle with the equipment.

The control unit has a digital display that shows RPM and settings clearly — no guessing what the motor is doing. It’s compact and doesn’t take up much bench real estate. The handpiece is balanced well and keeps heat and vibration away from your hand during long runs, which is something you appreciate more the longer the session goes. For specialists who work with demanding materials daily and need a motor that keeps up, the PRIME 115 delivers where it counts.
