High Speed Brushed Gear Motor 12V/24VDC for Automatic Machines 40W
Quick Detail:
Type: Worm gear DC Motor Voltage Power: 12/24VDC, 40W
Construction: Permanent Magnet Structure and Working Principle: Brushed
Operating Speed: High Speed Gear material: bronze
Application: Universal, Industrial, Household Appliances, machine power system
Description:
The Brush DC Motor stator is stationary, while the rotor rotates with respect to the Brush DC Motor stator. When power is applied to the Brush DC Motor rotor windings, the polarity of the winding and stator magnets is misaligned, and the Brush DC Motor rotor rotates until it is almost aligned with the stator magnets. As the Brush DC Motor rotor reaches alignment, the brushes in the Brush DC Motor move to the next commentator contacts, and energize the next winding. This results in a current reversal, thus causing the winding and Brush DC Motor stator magnets to misalign again. This process repeatedly is what keeps a Brush DC Motor rotating.
Applications:
The Brush DC Motor is particularly a favorite in the automotive industry because of its simplicity and affordability. Many automotive manufacturers use them for power windows, seats, etc. However, the Brush DC Motor can be found in nearly every industry ranging from computers to manufacturing.

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
