A Portescap 16DCT Athlonix ironless DC motor with precious metal commutation is a good fit in this example, because it supports a maximum continuous power of up to 4.2 W (Fig. 2).

Figure 7 The waveforms show motor-supply voltage and current with frequency clamping. Source: Texas Instruments. The inclusion of a simple clamp circuit satisfies the goal of starting up a DC motor ...

He even gets his motor up to 12,500 rpm with his homebrewed drive circuit. Making your own motors can help you solve some difficult engineering challenges, like building motorized rollerblades .

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...
