How do I choose a motor for my job application?

Consider an application’s purpose and which current it uses to select the appropriate type of motor. An application’s specifications such as voltage, current, torque, and velocity will determine which motor is most appropriate so be sure to pay attention to its requirements.

When selecting a motor for an application the first consideration should be?

Speed control

The first consideration in choosing a motor control technology is the speed control requirements. Some soft starters have limited slow-speed control between starting and stopping. Slow speeds can vary from 1 to 15 percent of the full speed and can be used in a maintenance or alignment operation.

How do you specify a motor?

Identify if the motor is single or three phase – this should be detailed on the nameplate with the voltage supplied to the motor. Identify the power rating or kilowatt kW reading. If the power is given in horsepower (hp), multiply by 0.75 to give the power in kilowatts.

How do I choose a pump motor?

When choosing a motor for a centrifugal pump, you must consider the impeller size, maximum capacity, specific gravity of the fluid, and service application in case API requirements apply. If you take these things into account, you will select the right motor for your centrifugal pump application.

How motor power rating is selected?

Continuous duty and variable load

the duty cycle is closely related to temperature and is generally taken to include the environmental factors also. v The rating of a machine can be determined from heating considerations. v However the motor so selected should be checked for its overload capacity and starting torque.

Why is it important to choose a motor according to application purpose?

A properly sized motor must be able to turn the load from a dead stop (locked-rotor torque), pull it up to operating speed (pull-up torque), and then maintain the operating speed. Motors are rated as one of four “design types” for their ability to endure the heat of that starting and pull up.

How does a simple motor work?

This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.

  2. Ambient Temperature and Environment. …
  3. Shock Load or Type of Load. …
  4. Output Style or Mechanism. …
  5. Output Shaft or Hollow Bore Size. …
  6. Housing Styles.

How do I know what size motor I need for my project?

Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the newly required torque. This will help you narrow the choices down to a few select motors.

How do you size a motor?

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.
