Note 1: The braking torque values shown in the above table are the static friction torque values. Dynamic friction torque values will be
approximately 80% of the static friction torque values.
Note 2: At starting first operation or after replacing the brake lining, the braking torque may be less than the specified torque. In this case, fit the
friction surfaces of the brake by applying the brake several times with a light load
4） Rectifier specifications
Table 4 shows the standard specifications for the rectifier (for the 200V type).

screws into the threaded holes of the side plate. The machine screws will push the Armature
to release the brake. At the completion of manual brake releasing, be sure to reset the brake.
Notes: To manually release the brake, observe the following items:
Be sure to check that the brake is properly released.
Basically, reducing the gap to zero will release the brake. To check whether the brake is released,
manually turn the motor shaft. If you can turn the shaft, judge that the brake is released.
If a large tightening force is applied to the simplified manual brake release bolt, the Armature or
side plate may be distorted or damaged, and normal operation may not be possible. For this reason,
carefully tighten the manual release bolt.
If the manually released brake is not reset, do not operate the motor. Before starting full-scale
operation, be sure to check that the brake functions properly.
For simplified manual brake releasing, up to 50 times of releasing is allowable.
・ On the top of the fan cover, there is a brake release lever.
b） One-touch manual brake releasing (optional)
Turn the lever 90°to release the brake. (Do not turn the lever
more than 90°. The brake may not be released.) At the
