● When the motor is approved under various safety standards, the model name on the nameplate is the approved model name.
● Contains a built-in thermal protector (automatic return). If a motor overheats for any reason, the thermal protector is opened and the motor stops.
● When the motor temperature drops, the thermal protector closes and the motor restarts. Be sure to turn the motor off before inspecting.
● Note: "-A" it means the voltage 110V, the assembly capacitor value it is according to the label.

■ Wiring  Diagram

-SW1 operates both motor and electromagnetic brake action. (Switched simultaneously)
-The motor will rotate when SW1 is switched simultaneously to ON.
-When SW1 is switched simultaneously to OFF, the motor stops immediately with the electromagnetic brake and holds the load.
-If you wish to release the brake while the motor is stopped, set the SW1 to off and connection point at the side of black lead to ON.

Direction of Rotation.
To rotate the motor in a clockwise (CW) direction, turn SW2 to CW.
To rotate the motor in a counterclockwise (CCW) direction, turn SW2 to CCW.

■ Features For  Power Off Activated Type Electromagnetic Brake Motor

1.Structure and operation principle
Table 3 is the structure for the electromagnetic brake motor. We produce the power off activated type. Exerting the voltage on the winding, it will magnetize the armature pressed by the spring. The motor will be in a stage of rotating, when there is a backlash between the armature and brake rim. Once the winding voltage is cut down, under the influence of spring, the armature press the brake rim, which will create a brake force. Then the motor gets to a stop.
2.The characteristics of the electromagnetic brake
It is an AC power off activated type electromagnetic brake which is connected directly with the motor. It will get to a blink stop and keep load when the supply is power off. It will keep the torque between 0.05~2.0Nm. It is especially suitable for the safety brake in the circumstance of unconsciously power off.The electromagnetic can change its direction frequently. It can be stopped 6 times in a minute. But be sure that it lasts for 3 seconds or more.
After we set a commutating loop in the brake, it can share the power supply with the motor.
※The value is standard. It will be change in different condition. When actually used, be sure to make the surface temperature of the motor less than 90°C.
3.The features for the starting time and brake time
The starting time means the time for the motor's starting time plus the electromagnetic brake release time. The brake time means the time from power cut off to the time of motor completely stop. The over-run, starting time and brake time will be different according to the different applications.
