W70
micro motor
W series brake is a kind of spring pressure type electromagnetic power loss brake, which is specially equipped with micro motor to decelerate and maintain braking. It is widely used in machine tools, manipulators, printing equipment, textile machinery, packaging machinery, stage lifting equipment, non-standard automation, medical equipment, testing equipment, automobile manufacturing, satellite communication, metal processing, pharmaceutical industry and other industries.
Key Features
● For deceleration and braking
● Low noise, low brake sound
● Small volume to achieve large torque
● Torque range 0.25-2(N. m)
● Long service life
● Use imported high wear-resistant friction plate, durable
● Meet the use of high temperature environment
● Brake operating environment temperature -10 ~ +40(℃)

1. The brake is mostly made of soft materials. Avoid knocking, dropping or using too much force during installation, otherwise it may cause scratches or deformation of the brake and affect the use. Please pay attention during installation.
2. Please note that the lead wire of the brake is not stretched by force, and the lead wire is bent too much or picked up by hand, which may damage the lead wire and cause the brake to fail to work.
3. Our brakes are dry double-sided friction plate brakes. If the friction surface is stained with oil or water, it will cause the torque of the brake to drop, so it needs to be used in a dry state. In order to prevent oil or water and dust, please use a protective cover.
4. Excessive voltage fluctuations will affect the performance of the brake, so the use of the brake voltage control in the range of ± 10% of the rated voltage, and requires smooth and no interference.
5. The working clearance of the actuator has been adjusted when leaving the factory, so there is no need to adjust it when in use, and the user is requested not to open the brake without permission. If the gap is not appropriate, the brake may not work properly.
6. Special attention: when the motor rotates, the brake must be opened, and forced drag with brake is not allowed! Drag with brake will damage the brake in a short time!
7. The installation screws are required to be fixed with special glue for thread. When applying glue to the screws, please be careful not to apply it to the surface of the rotor and the surface of the square wheel.
8. The installation accuracy of the brake is not good, which may cause the brake to make noise during operation. Please pay attention to control. The allowable values are shown in the following table:
| allowable value | Seat Number | |||||
| 20 | 30 | 40 | 50 | 60 | 70 | |
| T | 0.2 | 0.2 | 0.2 | 0.3 | 0.3 | 0.3 |
| Z | 0.02 | 0.02 | 0.03 | 0.03 | 0.04 | 0.04 |
