Question 2Electricity/Electronics - QMED70% to pass
Which of the following conditions will occur if the brake solenoid coil burns out on a cargo winch with an electrical brake?
AI Explanation
The correct answer is C) The brake will be set by spring force.
When the brake solenoid coil burns out on a cargo winch with an electrical brake, the brake will be applied by the spring force instead of being held open by the energized solenoid. This is a fail-safe design, where the brake is normally set and requires power to be released. With the solenoid coil burned out, the lack of energization will allow the spring to set the brake, preventing the load from falling.
The other options are incorrect because: A) the winch will not continue to operate as usual without a functioning brake; B) the motor will not overspeed since the brake will be applied; and D) the load will be held in place by the applied brake rather than falling.
