4) There is a DC ammeter with a measuring range of 0-±5A, and 3 is a half-digit display.

There are three-pole 220V power sockets on both sides of the control panel.

2. DQ02 experimental table and stool

The experimental table is made of iron with a double-layer matt dense spray-p*nted structure. The tabletop is made of fireproof, waterproof and wear-resistant high-density board. It has a solid structure and is shaped like a rectangular closed structure. It has a beautiful and elegant appearance; it is equipped with two large drawers and cabinet doors. , used to place tools, store pendants and information, etc. The desktop is used to install the power control panel and provide a spacious and comfortable work surface. The experimental table is also equipped with four universal wheels and four fixed adjustment mechanisms, which are easy to move and fix, and are conducive to the layout of the laboratory .

3. DQ03-1 motor guide r*l, tachometer generator and intelligent digital display tachometer

Including tachometer generator and guide r*ls for fixing the motor, etc. The guide r*l has good flatness, no stress deformation, fine processing, good concentricity, and good interchangeability. It can ensure that the concentricity between motors and motors, and motors and dynamometers does not exceed ±5 wires. The motor operation noise is small, and the experiment The parameters are typical and can better meet the experimental requirements.
