Current going to an electrically operated motor brake

Current going to an electrically operated motor brake

• A. It generates a magnetic field to activate the brake
• B. It causes the brake pads to retract
• C. It squeezes the inner and outer friction discs together
• D. It speeds up rotation of the brake rotor

Answer: (C)

When current is applied to an electrically operated brake, the electromagnet creates a magnetic field that pulls the brake components together. This action squeezes the inner and outer friction discs, generating friction against the rotor and producing braking torque. That clamping motion is the actual mechanism that slows or holds the shaft. The other options describe effects that don’t result in braking (retracting the brake pads or speeding up rotation) or only mention the field itself without the engaging squeeze.
