<\/figure>\n\n\n\nDC motors come in a variety of sizes. It\u2019s critical to know which size will work for your specific application.<\/p>\n\n\n\n
A DC motor is an electrical device that converts electrical energy into mechanical energy. The most common use of a DC motor is as the power source for an electric vehicle such as a car, bus, or train.<\/p>\n\n\n\n
Some key factors to consider when choosing a DC motor are:<\/p>\n\n\n\n
- Voltage<\/li>
- Current<\/li>
- RPM (rotations per minute)<\/li>
- Torque (turning force)<\/li>
- Weight<\/li>
- Mounting type<\/li>
- Speed control<\/li><\/ul>\n\n\n\n
The importance of understanding speed and torque<\/strong><\/h3>\n\n\n\n
The size of the motor determines the power and torque that it generates. As you might expect, larger motors generate more power and torque than smaller ones. <\/p>\n\n\n\n
That\u2019s why you\u2019ll find larger motors in heavy machinery like trucks, trains, and construction equipment. Smaller DC motors<\/a> are often used in tools such as drills, saws, and sanders.<\/p>\n\n\n\n
Torque is the force that a DC motor can exert on its load. A motor with high torque will be able to lift heavier loads with less effort than a motor with low torque.<\/p>\n\n\n\n
Speed, rather, determines how quickly a DC motor can move its load. A higher speed means the load will move more quickly, but it\u2019ll use more power in doing so.<\/p>\n\n\n\n
The speed of a motor is measured in RPM or rotations per minute. Torque is the force that causes rotation, calculated by multiplying the torque by radius.<\/p>\n\n\n\n
As such, it\u2019s critical to understand speed and torque when shopping for new DC motors for your business\u2014for example, a small motor designed for power tools won\u2019t perform well (or at all!) in construction equipment or machinery. <\/p>\n\n\n\n
