hey, can someone please explain what exactly is d c motor running on no-load?
dummie said:what happens if commutator is not placed on magnetic neutral plane?
dummie said:does no load means that the armature draws no current from the supply.as current drawn by armature is dependent on load torque
hey, can someone please explain what exactly is d c motor running on no-load?
dummie said:i have this very stupid doubt but i need to ask this.
what does we actualy call load. In some texts that i have referred , the current supplied by,say, alternator is called load while in others the active power supplied by the alternator is called load.
so what should i understand the load to be?
A DC motor is an electrical device that converts direct current (DC) electrical energy into mechanical energy. It consists of a stator (fixed part) and a rotor (rotating part) that work together to produce rotational motion.
No-load refers to the condition where a motor is running without any external load or resistance on its shaft. In this state, the motor is not doing any work and is rotating freely.
When a DC motor is running on no-load, an external power source supplies a constant DC voltage to the motor, which creates an electric field. This electric field interacts with the magnetic field of the motor, causing the rotor to rotate.
Running a DC motor on no-load allows for testing and calibration of the motor's speed and performance. It also helps to identify any issues with the motor, such as excessive noise or vibration, before putting it under load.
No, running a DC motor on no-load does not cause any damage as long as the voltage and current are within the motor's rated limits. However, running a motor on no-load for extended periods can cause it to overheat, leading to potential damage. It is important to monitor the motor's temperature while running on no-load and not leave it unattended for long periods.
