High Strength 24V PMDC Brushed Electric Motor with Bronze Gear for Automation Machinery
Description:
In an electric motor the moving part is the rotor which turns the shaft to deliver the mechanical power. The rotor usually has conductors laid into it which carry currents that interact with the magnetic field of the stator to generate the forces that turn the shaft. However, some rotors carry permanent magnets, and the stator holds the conductors.
Electric motors operate on three different physical principles: magnetic, electrostatic and piezoelectric. By far the most common is magnetic.In magnetic motors, magnetic fields are formed in both the rotor and the stator. The product between these two fields gives rise to a force, and thus a torque on the motor shaft. One, or both, of these fields must be made to change with the rotation of the motor. This is done by switching the poles on and off at the right time, or varying the strength of the pole.
Applications:
Electric DC Motors have a wide variety of uses and are found in cars, clocks,drills, fans, fridges, hair dryers, toothbrushes, vacuum cleaners,water pumps (for fish tanks, central heating, fire fighting) washing machines, hard disk drives, DVD players, electric vehicles and industrial equipment including extruders,fork-lift trucks, lathes, mills, hoists, robots and winches.

Competitive Advantage:
- Low Initial Cost - The initial cost of an electric motor is considerably lower than a fossil-fuel engine with the same Output Horsepower Rating (in nearly every case).
- Long Life - Because electric motors contain relatively few moving parts, they have extensive operational life spans. For instance, an appropriately selected and maintained electric motor offers up to 30,000 hours of operating life without major repairs. (This is the approximate equivalent of 3½ years of perpetual usage.)
- Low Maintenance Requirements - Electric motors are durable and have extensive operating life and minimal service requirements.
- High Efficiency - Electric motors are highly-efficient with ratings that range from 50% to 95% (depending on the motor's size and operating conditions).
