Sinfonia Non-excitation electromagnetic brakes - Spring closed brake
Non-excitation (negative actuation) spring close electromagnetic brakes use a reliable multi-spring mechanism to apply braking force after power is cut off.
Overview
The design of this redundant system offers very high reliability, making it ideally suited for as a holding brake or emergency stop brake.
The 3 standard series are: SBR, which is best suited to use in servomotors or robotics applications due to its ultra-thin, projection-free design, SBM, best used as an easily-mounted general-purpose motor, and SBS, which is versatile enough to suit every application.
Features
SBR type | Ultra-thin and projection-free | Best integrated into servomotors, special small motors, robots, or FA machinery as a holding or stop brake. |
Provides silent operation, free from metallic noise by eliminating metal from our disk structure. | ||
SBM type | Easily mounted and able to withstand heavy operation | Easily mounted to general-purpose motors, abrasion resistant and dissipates heat efficiently. |
Becomes a brake motor when mounted to a general-purpose motor. | ||
SBS type | Versatile and easy to use | By using a multi-plate design, we are able to achieve high torque with a small diameter, making this suitable for breaking and emergency stops in many applications. Additionally, the static frictional torque can be varied by changing the number of disks. |
