Working principle of electric standing desk

The lifting column of the electric standing table adopts 24 V DC as the power supply

The 24 V permanent magnet DC motor is used as the driving power source

After 24 V DC power is supplied to the motor, the motor rotates and decelerates through the worm and turbine of the motor

A nut is fixed on the inner tube. After the screw rod rotates, the nut moves forward and backward on the screw rod, so that the inner tube moves forward and backward

By switching the positive and negative poles of 24 V DC, the motor will rotate forward or reverse, so that the inner tube is forward or backward

By changing the thread pitch of screw rod and nut, the maximum thrust and speed of push rod can be changed.
