The governor has changed a new one, with the governor to zero, but the motor is still turning! The motor has a different sound, such as the sound of iron and iron friction!
You start the static logic and set the dead area to a larger point.I hope my answer will help you.
Check the speed line. There may be a circuit breakers. There's no problem with the excitation coils. The motor is abnormal and the bearing is damaged.
This is basic rule out the problem of speed governor, the problem may be broken in speed resistance speed governor is set to zero, the resistance should be in maximum, or feedback signal input connection circuit, it is suggested that can be replaced. Speed machine: governor (called) is a kind of automatic adjustment device, according to the change of the diesel engine load, it automatically increase or decrease in fuel injection pump oil, the diesel engine to run at a steady speed. Governor has been in the industry dc motor speed regulation, conveyor belt speed, lamplight illume mediation, computer power supply cooling, dc fan, etc., used widely. Governor according to its working principle is different, can be divided into mechanical, pneumatic, hydraulic, mechanical pneumatic compound, complex mechanical hydraulic and electronic, and other forms.
The governor has changed a new one, but the motor is still turning! This is basic rule out the problem of speed governor, the problem may be broken in speed resistance speed governor is set to zero, maximum resistance should be in, or associated feedback signal input lines (including feedback coil winding) local open circuit or short circuit. This self should have a multimeter check.
