Integrated Motors Simplify Motion Control

With machines getting more robust, smaller, less expensive and more reliable, engineers are facing the challenges of designing newer types of motion control. One way of addressing such motion control challenges, without being an expert in mechatronics is to use integrated motion control systems. Typically, these solutions combine the motor, the drive and the system components within a single unit. The system components include the intelligence or motion controller and input outputs all onboard. The Read more [...]

Efficient Control of Motors at Low Speeds

When a motor is operating at high electrical frequency or high mechanical speed, the back EMF signal generated by the rotating rotor presents an efficient feedback technique for a sensor less motor control. However, generation of the back EMF requires a minimum frequency and that makes it difficult to control motors running at low speeds. The process of continuously estimating the rotor flux angle at zero and very low speeds, together with stably moving between low-speed and high-speed estimators Read more [...]

A new 32 HD motor for rough operations

Maxon Precision Motors, Inc. based in Fall River, MA, has successfully designed a new 32 HD motor for rough and abusive operations. Known as the EC-4pole 32 HD motor with part number 397798, the motor is considered ideal for operating in conditions existing in deep drilling. Exploration in gas and oil fields is known by the name “downhole drilling” and according to deep drilling technology, it is possible to recover oil and gas even from depths of 2500 meters or more. This 32 HD motor is being Read more [...]

What is a brushless DC motor?

Most electrical appliances have an electric motor that rotates to displace an object from its initial position. Various motors are available in the market such as servomotors, induction motors, stepper motors, DC motors (both brushless and brushed), etc. The choice of a motor depends on the requirements of an application. Most new designs favor brushless DC motors, also referred to as BLDC motors. The working principle of brushless DC motors is similar to that of brushed DC motors, but their construction Read more [...]
