A Direct Current (DC) motor is a motor that turns energy from a direct current and turns this into mechanical energy. The first DC motor was developed around the 1830’s-1840s. They were commercially unsuccessful, because these motors were battry powered and batteries were still very expensive and the quality was low. When the electrical grid was created and the rechargeable batteries were invented in the late 1800s this all changed. The first commercially viable DC motors entered the market. Some examples of applications in which they are still used are:
- Machine tools
- Air compressors
- Motor starters in cars
DC motors have been improved continiously, but other types of motors, like the BLDC motor, have been developed in the mean time too. As a result, the use of brushed Direct Current motors in several applications is limeted today.
