Application

Motors can be constructed in several different physical configurations. In the conventional (also known as inrunner) configuration, the permanent magnets are part of the radially center core. In the outrunner (or external-rotor) configuration, the radial-relationship between the coils and magnets is reversed. The stator coils in the outrunner configuration form the center core of the motor, while the permanent magnets spin within an overhanging rotor which surrounds the core.

Significance Of Back EMF

When the motor is operating then the concept of generator comes into the picture i.e., whenever the flux linking with the conductor changes then there will be an induced emf in the conductor. Here, the flux produced by the poles will be stationary and constant and because of the motor principle, the armature starts rotating.

Because the armature starts rotating the flux produced by the main field will be cut by the armature conductor and therefore there will be an induced emf in the armature conductor according to the generator principle.

We know that the direction of the induced emf produced by the motor is opposite to the applied voltage. But the magnitude of the induced emf will be similar to that of the induced emf of the generator.

Features Of Products

• Highly Standard Modular Designed: The products are connected with and driven by different types of motors or other kinds of input power .The same type geared motor can be adapted to optioned powers of motors. It is therefore easy to realize different solutions for varied requirements.
• Ratio: Featured many closely divided ratios and wide ranges of them. Very big final ratios can be obtained through combined unites to reach extremely low output speeds.
• High Strength, Compact Dimension: Housings are made of high strength cast iron. Gears and shaft gears are finished with gas carburising process and precise grounding to sequentially get high loading capacity of per certain volume.
• Long Service Life: Under the conditions of accurately selecting type size and the normal maintenance and use, main components ( except those easily-disabled parts ) can last as long as up to more than 25,000 hours. Easily-disabled parts include lubricating oil, oil seals, and bearings.
• Low Noise: All key components are finished by precisely machining, accurate assembly, and finally tested, and therefore, fairly low noise is reached.
• Highly Efficiency: The efficiency of gear unit is more than 95%, The efficiency of worm gear unit can reach 89%. 8,Large Radial Loading Abilit.
