What is the breakdown torque?

breakdown torque. The maximum load that a given motor can move, measured in amps. Breakdown torque is the highest torque a motor can attain without stalling.

What causes breakdown torque?

Breakdown torque is the maximum torque that an AC motor develops with rated voltage applied at rated frequency without causing sudden drops in speed. This is also known as pull-out torque or maximum torque. The torque required to produce rated power at full-load speed.

What is pull out or breakdown torque?

Pull Up Torque (PUT) is the minimum torque developed by the motor as it accelerates from standstill to the speed at which breakdown torque occurs. Break Down Torque (BDT) is the maximum torque that the motor is capable of developing.

What is breakdown torque of synchronous motor?

Breakdown torque is the maximum torque of the motor, which is produced at full rated voltage and frequency. Torque T is directly proportional to P. As power varies as applied voltage V, a torque of a synchronous motor is also varying as applied voltage V.

What is load torque?

Load torque is the amount of torque constantly required for application and includes friction load and gravitational load. The faster the load needs to accelerate, the higher the acceleration torque is. Sometimes the load torque is higher; sometimes the acceleration torque could be higher.

Should torque be high or low?

Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms. This is also why people talk about “low-end torque” being important for better power at slower speeds.

What do mean by torque?

Quick facts. In physics, the definition of torque is a force that acts on a body through a lever arm. Applied to internal combustion engines or electric motors, torque indicates the force to which the drive shaft is subjected. Torque is expressed in pound-feet (lb-ft) or newton-meters (Nm).

What is nominal torque?

The nominal torque is therefore the maximum permissible continuous torque that may act on the output shaft of the actuator. The nominal torque is determined by the continuous power of the electric motor, or by the continuous load of the attached gear unit.

What do you mean torque?

Torque is a twisting or turning force that tends to cause rotation around an axis, which might be a center of mass or a fixed point. Torque is sometimes confused with work, which is defined as force applied over a distance. However, torsion (twisting) is integral to the definition of torque.

What is torque and its type?

Torque is the measure of the force that can cause an object to rotate about an axis. Hence, torque can be defined as the rotational equivalent of linear force. The point where the object rotates is called the axis of rotation. In physics, torque is simply the tendency of a force to turn or twist.

What is good torque for a motorcycle?

Normal horsepower ranges for full-size motorcycles are probably between 15 and 200 horsepower. (Yes, exceptions exist, but most will fall within that range.) Torque specs will usually ring in at 10 to 175 foot-pounds. In general, the bigger the torque number is, the stronger a bike will feel low in the rev range.

What is the law of torque?

Essential to proving Kepler’s second law (and further laws) is the concept of torque. A torque is a tendency to change something’s state of rotation; it is the rotational analogue of force.

What is full load torque?

Full load torque is the name plate or rated torque of an induction motor. This indicates if the motor is run under normal operating condition it can deliver up to the full load torque without having any issue in the motor.

What is pull out torque?

Pull-Out Torque is the maximum sustained torque, which the motor will develop at synchronous speed without stepping out, with rated voltage applied, at rated frequency and excitation.

What is pull up torque?

The pull-up torque is the minimum torque the motor will produce while accelerating to operating speed from rest.
