Machine features

Machine Features

  • Ease of use.

Machine features1

Machine Features

  • It has a good flexibility.

Electrical circuit

Electrical Circuit

  • Ease of operate machine.

  • Control the time of experiment .

  • Give accurate results for number of cycles to failure .

  • Support safety for both user and machine .

Electrical circuit2

Electrical Circuit

Safety mode

  • The motor does not work until:

  • The main switch is ON.

  • Emergency switch and (ON/OFF switch) are ON.

  • Cover of the motor is completely closed.

Electrical circuit3

Electrical Circuit

Accuracy in reading results

  • To get the accuracy in results.

  • The normally open limit switches are ON.

  • The normally closed limit switches are ON.

  • Then sensor feeds signals.

Electrical circuit4

Electrical Circuit

  • Open limit switches are ON means the cover of the motor is closed, the house is not aligned, does not happen any failure in the specimen.

  • Closed limit switches are ON means, the contactor start connecting, and there is a load affecting on the specimen.

Electrical circuit5

Electrical Circuit

  • When start getting signals from the sensor,

  • counter counting until the specimen fails,then:-

  • The motor stop rotating,

  • Sensor stop feeding with signals,

  • And the counter holds the values on.
