Fundamentally: power = torque x rpm Power and torque both make noise, but they are different in how they are measured and what they mean. Torque is not related to time. Power is a time-related rate. Most engineers talk about torque when they need to understand how much force is applied from a dead stop. It is force X radial distance. Huge torque may have very little power (in HP or Watts) behind it. Imagine a really strong guy with a really long wrench unfastening a bolt. He can develop lots of torque, but ultimately he can put out very little power (about 1/4 HP or 185 W for humans) over an extended time.
What else can I help you with?
How does the shaft work in this machine?
The shaft in this machine rotates to transfer power from the motor to other parts, allowing them to move or function.
Determine the maximum torque the shaft can transmit?
The maximum torque a shaft can transmit depends on the material, diameter, and length of the shaft as well as the operating conditions such as speed and applied load. To determine the maximum torque, you would need to perform a detailed mechanical analysis or consult engineering specifications for the specific shaft in question.
What is a shaft in mechanics?
A drive shaft is a tubular piece of pipe, usually made of metal. The shaft extends from the back of the transmission to the real axle and is considered part of the drive train. It is what delivers the power from the motor and transmission to the rear axle and tires.
What is the torsional rigidity of a shaft?
Torsional rigidity of a shaft, also known as torsional stiffness, refers to the shaft's resistance to twisting under an applied torque. It is a measure of how much the shaft twists relative to the applied torque. Torsional rigidity is important in applications where precise torque transmission is required without excessive twisting or deformation of the shaft.
What is the shaft work formula used to calculate the work done by a rotating shaft?
The shaft work formula used to calculate the work done by a rotating shaft is: Work Torque x Angular Displacement.
Is there anyway it increase the power out put of a motor?
The power output of a motor can be changed by the use of gears. Gears can be used to increase torque by reducing the speed of the output shaft by placing a large gear on the output shaft, coupled to a smaller gear. Conversely, by using a small gear on the output shaft, coupled to a larger gear, the speed can be increased with a reduction in torque.
How motor kw is been decided?
You can measure the output power of the motor (mechanical power or shaft power) by a speed and torque sensor. The product of speed (angular velocity to be precise) and torque is power. Is this case the output power. The SI unit of power is W, kW is 1000 W. So the power/1000=power [kW].
How do you calculate shaft power?
Shaft power P = (2(pi) * (angular Speed in rpm) * (Torque at shaft)/ 60 Torque of a solid shaft is given by (pi/16)* (Shear stress of material of shaft) * (Dia of shâft3).
What is the loading arrangement used in dc motor?
the loading arrangement used in normal electrical machines is brake drum - spring balance arrangement. This is used to calculate the torque and output power. the formula for torque is 9.81*(diffference between the spring balance) * radius of brake drum. thee output power obtained is 2*π*motor speed*torque obtained
What is motor current at zero RPM in vacon nxp ac drive?
Zero rpm at the drive does not exclude the presence of a holding torque on the shaft of the motor due to load in some circumstances. The motor current will be a reflection of the torque presented at the shaft.
What is meant by load on a motor in eletrical engineering term?
The load on a motor can be measured in watts, and it is the mechanical torque supplied, multiplied by the speed of the shaft. When the torque is in Newton-metres and the speed is in radians/second, the mechanical power output result is in watts.
What is Friction in induction motor?
Friction is present at the motor shaft and also in various parts of the load. The friction torque is equivalent value of various friction torques referred to the motor shaft.
Who invented the drive shaft and when?
A drive shaft allows torque to enter a motor. Louis Renault of France was the inventor of the drive shaft. He invented the drive shaft in 1898.
What is torque in Electricals?
The electrical equivalent to torque is AMPS. Power in Electricity is Volts * Amps Where in a rotating shaft its RPM * Torque
How does an induction motor develop torque?
The shaft of an AC induction motor rotates because of the torque created by the interaction between the magnetic field of the stator and the magnetic field of the rotor.
When power a fan using a simple electric motor the fan's shaft and blades are attached to?
Fans shaft and blades are attached to rotor shaft of the motor
What is motor shaft speed?
Motor shaft speed refers to the rotational speed of the motor's output shaft in revolutions per minute (RPM). It indicates how fast the motor is rotating and is a key parameter in determining the mechanical power output of the motor. Motor shaft speed is influenced by the frequency of the electrical power supplied to the motor and the motor's design specifications.
