High Torque DC Brush Gear Motor 12V for Auto Garage Door Openers
Description:
Brushed DC motors can be varied in speed by changing the operating voltage or the strength of the magnetic field. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brushed motor can be altered to provide steady speed or speed inversely proportional to the mechanical load.
Applications:
Although the brushless DC motor has surpassed the Brush DC Motor because of its longetivity and reliability, the Brush DC Motor is still appropriately chosen for many applications. Most commonly, the Brush DC Motor is found in household applications. It can also be found in the industrial world because of its versatility in altering its torque to speed ratio.

Competitive Advantage:
• The Brush DC Motor has a simple construction, therefore may not require a controller. When a controller is chosen, it is typically a simple and inexpensive drive design.
• Understandable design technology facilitates in the quick application of the DC Brush Motor
• The design of the Brush DC Motor is quite simple, in that a permanent magnetic field is created in the by either of two means; permanent magnets or electro-magnetic windings
