A.G Brake Motor introduction & application
AXIAL AIR GAP BRAKE MOTOR
There are 3types of structure, normal type, air lock type and Gondola type. AXIAL AIR GAP BRAKE MOTOR is used for precision machine tools by high braking torque(350%). Air Lock type has strengthened the braking function by adding a pneumatic cylinder in the conventional brake method. Gondola type is connected cable and has cap for protect switch

Allowable Pressure Load
When connecting the motor, the weight to be loaded on the shaft and the overhang weight should not exceed the allowable pressure load weight (follow the table bellow).
| Output | Pole | Thrust Weight |
Overhang Weight |
|---|---|---|---|
| 0.1Kw | 4 | 25 | 30 |
| 0.2Kw | 4 | 30 | 40 |
| 0.4Kw | 4 | 30 | 40 |

| 1.5Kw | 4 | 70 | 90 |
| 2.2Kw | 4 | 70 | 90 |
Caution
When fixing gears, pulleys and sprockets to the shaft, use shrink fit method, not the hammer fit method to prevent impact to the shaft.

Brake linings wear out after long-term use, and the use of worn linings causes performance degradation. Brake ling wear is related to usage time. load value(GD2), motor capacity, and condition of operating. Refer to the graph below and replace the lining according to the allowable brake braking time of each motor.
