Question: How do you select a project motor?

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 I choose an electric motor?

To determine the technical specifications, it will be necessary to determine the power, torque and speed of the motor. In order to determine the size, you must know how much space the motor will take up and how it is mounted (i.e.how it will be fixed in the system).

How do you select a project for a DC motor?

Key criteria for selecting a DC motor includes first finding out what voltage is readily available for the application and what physical size the motor needs to be. Speed and torque can then be considered once these first two parameters are determined. 1. Voltage availability is a critical element in motor selection.

What are the criteria for selecting a motor for particular operation?

Motor Selection

  • Speed.
  • Torque.
  • Motor connection interactions (i.e. what is the motor connected to and how does that influence its performance; Mecanum Wheel example given)
  • Speed-Torque Curve.
  • Mechanical Power.
  • Constant Voltage Torque-Speed Line.

How long can an electric motor run continuously?

In the range of six months to a year, you should expect the motor to run continuously for the life of the brushes. I thought the motor was too small to have its brushes changed by an electrician.

How do you select 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 do you select a motor for a particular application?

A constant or variable torque and horsepower will be required for the industrial motor depending on the type of load the motor is driving. The size of the load, the required speed, and acceleration/deceleration—particularly if it’s fast and/or frequent—will define the torque and horsepower that is required.

Which motor is constant speed?

A DC motor can be referred to as a constant speed motor because it can self- regulate its speed.

How do you select a motor based on torque?

The most critical consideration for selecting a motor in these cases is to choose one whose speed-torque curve exceeds the load torque curve. Loads from centrifugal pumps, fans, blowers, compressors with unloaders, and similar equipment tend to be variable over time.
