• The internal dental handpiece electric motor is an original Swiss brushless DC motor of which the running noise is as low as 45dB while the output torque is up to 3.5N.cm. (The largest torque of the famous brand in Japan NSK is 3.4N.cm. And the torque of the others is 2.5N.cm.)
• The motor is equipped with built-in high luminance cool color LEDs of which the luminance can be up to 7000LUX. The luminance can be increased or reduced according to the practical requirements, so that the doctors can accomplish the treatment under the most suitable conditions.
• The internal electric motor has four connecting modes: 1:1, 16:1, 20:1, 1:5. Motor with different speed ratio can be matched with different handpiece. Thus, it can realize different functions and applications according to the customers' requirements.
• The LED digital screen display can show the speed in real time, so the speed can be controlled precisely. With the additional sensitive touch screen, you can accurately adjust the speed of the motor according to relative buttons on the control panel. So the product can be more intelligent and humanized. It can satisfy requirements of different therapy.
• The American intelligent chip: the control box has built-in American control chip with intelligent program which is improved by several times, thus ensuring that the motor can run normally in any hostile environment. The chip also has the complete self repairing ability to ensure perfect running of the machine.
• The built-in design: the water and static proof circuit board is installed in the treatment table. The motor can be precisely controlled via the control panel in real time. When the user want to change the treatment table, you just need to pull out the connecting terminals. The operation is simple and convenient.
