[ edit ] Universal motors A series-wound motor is referred to as a universal motor when it has been designed to operate on either AC or DC power. The ability to operate on AC is because the current in both the field and the armature (and hence the resultant magnetic fields) will alt[r]
A batch type ginger washing-cum-peeling machine was developed and investigated for its use in the production line of bleached dry ginger. The machine used 2 hard nylon brush rollers that rotated at 200 rpm in opposite direction. The rhizomes got lifted and tumbled on the rollers, and the application[r]

In 1812, Faraday was hired as a bottle washer by the great chemist Humphry Davy. Later, Faraday became a greater scientist than Davy, making the last years of Davy’s life embittered with jealousy. Faraday made the first electric motor in 1821, a device th[r]
Động cơ bước (Step Motor) hiện nay rất thông dụng trong nhiều ngành công nghiệp khác nhau.

4. Regenerative braking control algorithm In conventional vehicles, the energy required to reduce velocity would normally be dissipated and wasted as heat during braking. On the other hand, HEVs have a regenerative braking system that can improve fuel economy. In an HEV, the braking torque is s[r]

When the motor cable between the AC motor drive and motor is too long, the layer insulation of the motor may be damaged.. Please use a frequency inverter duty motor or add an AC output r[r]
Any molecule will respond to the electric field, but some will respond dramatically, while others may respond quite weakly. This is of importance in designing new materials. The molecular electronic structure does not respond to a change in orientation of the nuclear magnetic moments, becau[r]
ACCELERATION – This parameter is determined by putting a step in current into the motor winding to bring the motor up to rated speed. The motor will accelerate exponentially. The acceleration is a measure of the rate of change of velocity over a peri[r]
The general theory of three-phase motors is often built based on the assumption that the three phases voltage is symmetrical. However, in practice, this operation mode of the motor cannot be achieved due to a number of reasons such as the structure of the motor is not symmetrical, the load in the el[r]
