What is the maximum torque than an induction motor can develop known as?
Gross Torque
Pull-out torque of induction motor?
The pullout torque is the maximum torque a motor can achieve. Also known as breakdown or peak torque. It occurs at the point where, the increase in the rotor current is exactly balanced by the decrease in the rotor power factor.
Is torque and current proportional?
Sometimes, for example in a separately excited dc motor. But in a series-wound dc motor the torque is proportional to current-squared, which gives the motor a very high starting torque and this makes series motors very popular for traction.
Which of the following Dc motor is suitable for high starting torque?
capacitor start motor
What type of motor is variable torque produced by varying the resistance of the secondary circuit?
Wound-Rotor
Explain Speed mode torque mode in variable speed drives in detail?
Torque mode in variable speed drives is where the drive adjusts its torque according to the input. The speed/velocity mode is where the input is used to control the motor's RPM.
What is meant by Reluctance Torque?
Reluctance torque is the torque generated in a reluctance motor due to the tendency of the rotor to align itself with the stator magnetic field. It occurs as a result of the variation in reluctance in the magnetic path between the rotor and stator. This torque is responsible for the motion of the motor and is one of the main torque components in reluctance motor operation.
How do you increase the torque of a variable frequency drive?
You can increase the torque of a variable frequency drive by increasing the drive's output voltage or current settings, adjusting the motor parameters to optimize torque performance, and utilizing advanced control features like field-oriented control to precisely regulate torque output. It's also important to ensure that the drive and motor are properly matched for the application to achieve maximum torque efficiency.
How you can improve the starting toque of the motor through variable frequency drive?
set the respective parameter for torque in the VFD.
What are the advantages of induction motor?
1. Induction motor has high starting torque, therefore use for operate pump which need high starting torque. 2. Induction motor operate on variable speed. 3. It can be used as generator when speed of motor is higher than synchronous speed.
How do variable speed motors work?
A variable sped drive is sometimes also known as a variable frequency drive. These drives are used in electro-mechanical drive systems to control AC motor speed and torque.
What is the function of vfd panel?
Variable frequency drive (VFD) panel is used to control the speed of an electric motor by varying the frequency and voltage of the power supplied to the motor. This allows for energy savings, smoother operation, and precise control of the motor's speed and torque. VFD panels are commonly used in industrial applications to optimize the efficiency and performance of motor-driven equipment.
What happens to a shunt motor when the starting torque required is too high at start-up?
If the starting torque required is too high for a shunt motor, it could lead to stalling or jerky operation at startup. This can cause overheating and damage to the motor windings due to increased current draw. It is important to match the motor's torque capabilities with the load requirements to prevent these issues.
Need of drives in motor?
Drives - I assume you are referring to Variable frequency Drives. The drives are useful when a motor needs to rotate at different speeds when in operation with out stopping it.
