Automatic Reel Winder 24V PMDC Brush Gear Motor ith Worm Gear Box
Description:
A Brush DC Motor provides simple speed control without the need of complicated electronics. The voltage applied to a Brush DC Motor is proportional to rotational speed, while torque is proportional to the current. By applying variable supply voltage, speed control can be achieved. Electronic speed controls have been developed to provide a more accurate and precise operation. Changing rotational direction can be done by reversing the field or armature connections.
Applications:
Brush DC Motors are used in a wide range of applications, ranging from toys to Jacuzzi pumps. Most automatic car windows and seat adjustments are operated by a Brush DC Motor. The Brush Motor has been an automotive industry favorite because of its relatively low cost and simple design. A Brush DC Motor comes in all different sizes, and torque and speed specifications. The Brush DC Motor can be a good candidate for virtually any motion control endeavor.

Competitive Advantage:
The Brush DC Motor has a relatively inexpensive start up cost and simple design. In some cases, the Brush DC Motor can cost half the price of their Brushless DC Motor counterparts. However, the brushes within the Brush DC Motor are apt to wear and require replacement, making it a higher-maintenance option, because of the long run costs.
