Micromotors dental For Sale

Tips for choosing a dental micromotor

The dental equipment market offers specialists a wide range of dental micromotors. When buying a device, there is a choice: to give preferences to expensive high-tech equipment or to save money, sacrificing performance quality. There is a third option, which allows saving money and buying quality equipment at the same time. But it is necessary to choose features and performance parameters correctly.

Scope of supply

A dental micromotor set includes:

1. A control unit which:

• controls an electric motor rotation speed;
• supplies low-voltage electric power to a handpiece;
• protects an electric motor against overheating and overloads.

2. A handpiece, which is used for:

• replacement instruments installation: brushes, mills, and drills;
• rotating instruments movement direction control (direct and reverse type).

3. A switch pedal, which performs the following functions:

• activates and deactivates a handpiece;
• controls an electric motor rotation speed.

Varieties

Dental micromotors are sold with handpieces of two types:

• brush or collector;
• brushless or collectorless.

In brush models, the magnetic field is created mechanically. In this case, the brushes slide on the contacts installed in the movable part of the micromotor. The stationary part in such devices consists of permanent magnets. They create a regular magnetic field. The magnetic field is electronically generated in the brushless units. The fixed part is equipped with an electric winding. When power is supplied to it, an alternating electric field is created in it.

Brush micromotors are simple and do not require a complex control unit. However, they are not so powerful and have a shorter service life. Brushless units develop the rotation speed of up to 50 to 60 thousand revolutions per minute.

Collector motors bear higher heat losses due to brushes friction against the collector. Therefore, care should be taken to withdraw excess heat and provide appropriate ventilation to prevent the motor overheating. Since it is forbidden to conduct large currents through collectors, such micromotors models will not provide high torque.

Brush models are suitable to work with low hardness materials. However, if you plan to process hard alloys in your dental clinic, it is better to buy brushless devices.

Universal selection parameters

The first thing you should pay attention to is the number of revolutions per minute. Each type of work requires different speed. Another important parameter to take into account is the torque. It is directly related to the micromotor. The higher this indicator is, the better it is.
