What to Know When Buying a DC Motor

Motors are ubiquitous in the field of equipment. This is not a lonely device. A reliable pump requires a reliable motor. The quality of the motor directly affects whether the equipment can operate normally. As the name implies, DC motors use direct current as their power source, while AC motors use alternating current as their power source. In terms of structure, the principle of DC motor is relatively simple, but in terms of performance, due to the stable speed of DC motor and accurate speed control, which cannot be achieved by AC motor, DC motor has to be replaced by AC motor under the strict requirements of speed. . AC motor speed regulation is relatively complex, but it is widely used because chemical plants use AC power. Motor type, soft start method, selection steps, damage cause and treatment method, difference between good and bad motors... These questions are all important reflections of the motor's happiness index.

What to Know When Buying a DC Motor

There are some basic things to consider before buying a DC motor, here are some key factors to consider: the higher the energy, the higher the torque, the energy keeps the net current flowing in one direction, check the recommended DC motor pull into the instruction manual. Current powers the motor, too much current is dangerous as it can damage the motor, make sure you understand its running and stall currents before using a DC motor controller. The speed is a bit complicated in terms of the motor, the motor is very efficient at high speed, but it can't be done if the gear is needed, and the addition of the gear does not limit the efficiency of the motor. Therefore, torque and speed reductions also need to be considered.

Why choose a DC motor?

When an AC motor is an option, a DC motor is highly recommended as the first choice, which has some advantages over an AC motor. For example, they are excellent when high starting torque is required to drive high inertia loads, and unlike AC motors , they easily control the speed of the DC motor. They are also ideal when DC motors need to be powered by low voltage DC sources such as solar panels or batteries. If you reverse direction quickly, you will find that the DC motor works fine. Unlike AC motors, DC motors can be started and stopped easily and quickly.

Application of DC Motor Controller

There are all kinds of DC motors on the market now, and we use them widely. At home, DC motors can be used in toys, tools and other household appliances. In industry, their needs include crossing carousels to conveyor belts, and reversing. DC motors are used to power pumps for their excellent sporty responsiveness and ease of shifting, and they are the preferred choice for fans due to their energy saving mechanism. DC motor toys come in a variety of voltages and therefore require different types of movement and speed. DC motors for electric vehicles are favored for their durability and energy efficiency. Both the rear and front hubs of e-bikes are equipped with DC motors to achieve the required power levels and torque.
