Oriental Motor - SB50W Brake Pack

Oriental Motor USA Corp

SB50W from Oriental MotorThe SB50W provides instantaneous stop, forward/reverse operation, electromagnetic brake control and open thermal protector detection functions integrated into one unit. These brake packs can sense when the thermal protector is opened, further ensuring the safety of your equipment. The SB50W can be used with induction motors, reversible motors, electromagnetic brake motors and watertight motors with an output range of 1 to 90 W (1/750 to 1/8 HP).

For use with:

  • World K Series - Induction, Reversible and Electromagnetic Brake Motors
  • V Series - Induction, Reversible and Electromagnetic Brake Motors
  • FPW Series - Watertight, Dust-Resistant Induction Motors

Instantaneous Stop
The electronic brake stops the motor instantly. A large braking force causes the motor to stop in approximately 0.1 seconds, allowing for an overrun of 1.0 to 1.5 revolutions. The braking current flows through the motor for approximately 0.4 seconds, after which the power supply to the motor is cut off automatically (the motor will lose its holding brake force).

Long Life, Simple Wiring and Maintenance-Free
The electronic brake operates on current flow, so it lasts longer than the mechanically operated electromagnetic brake that is subject to wear. This makes the SB50W ideal for indexing applications. The Electronic type input brake pack doesn't use a power relay so no maintenance is required. Wiring is easy as well.

Wide Voltage Range of 100 to 230 VAC
The SB50W covers a single-phase voltage range of 100 to 230 VAC ±10%, 50/60 Hz, accomodating all of the world's key voltage specifications.
