Permanent magnet direct current (dc) motors convert electrical energy into mechanical energy through the interaction of two magnetic fields. One field is produced by a permanent magnet assembly; the ...

A fundamental understanding of the speed-torque curve it the key to specifying a dc motor that will do everything it needs to do. Much has been written about the process of selecting motors for ...

A motor — or a generator — requires some normal magnets and some electromagnets. The usual arrangement is to have a brushed commutator that both powers the electromagnets and switches their polarity ...

The DCmind DC brush type motors feature a noise level of only 35 db − about the sound of a whispered conversation – and 20 db less than the current standard motor. The product includes 15, 25 and 55 ...

Chicago, Aug. 11, 2025 (GLOBE NEWSWIRE) -- The global brush motor market was valued at US$ 9.13 billion in 2024 and is expected to reach US$ 17.50 billion by 2033, at a CAGR of 7.50% during the ...

In my previous article, I described the four most common methods for motor and pump control: input voltage, input voltage pulse-width modulation (PWM), external PWM, and 0–5V DC analog speed input.

Preventive maintenance maximizes uptime while controlling costs. Maintenance crews strive to reduce maintenance costs and manage their workloads more effectively. Since DC machines require more ...

The TG3300 series slotless, brush PM motor employs a unique armature coil assembly that eliminates the iron core found in conventional motors. This design is said to eliminate cogging torque and ...

In the world of power tools, brushless motors are all the rage. While the technology isn't exactly new, it has gained traction in recent years due to some high-profile releases by Makita, Milwaukee, ...
