Oct 28, 2020 At present, the XPCS series of efficient double-rotor sand making machine has obtained the national utility model patent authorization. The processing capacity of this machine is 1600th, and the finished sand output is up to 750th. The two units that the customer ordered for the first time were installed and put into production in 2019.
double rotor machine with this improved structure is done through numerical design and evaluations for the same sizing. It is found that the motor constant square density. It is found that the double rotor switched reluctance machine is improved by 140 to conventional machine.
the machine performance compared to the conventional machine. As the drawback, the dual air-gap machine is not able to produce higher torque average and drags is presence for industrial application. Therefore, a novel through modification of magnetic circuit of the dual air-gap in double rotor switched reluctance machine is proposed.
The double rotor machine DRM can be applied as a mechanical diffe- rential gear. It is possible to m ake EMD using a synchronous m achine SM or an induction
One double is equivalent to two work efficiency.That is mean,if we use one YSCD6575 double rotor hammer mill to crush the 4-5t materials,it will cost one hour.Meanwhile,if we use two YSG6575 high efficiency hammer mills to crush the 4-5T materials is also costs one hour, The effect is the same in both cases.But the former takes up less space.
AbstractTwo magnetless double-rotor DR dual-mode machines, namely the DR DC-excited multi-tooth switched reluctance DR-DC-MSR machine and the DR ux-switching DC DR-FS-DC machine, are proposed for special direct-drive applications where two rotating bodies are required to operate independently. Both machines can
The DFIG can change the speed of the generator rotor by means of controlling the frequency of the rotor field current. When a fault occurs on the grid side and the rotor is accelerated, it can keep the speed of the rotor rotating magnetic field at the synchronous speed
When the double cage motor is running at normal speed, frequency of the rotor emf is so low that the reactance of both cages is negligible. The two cages being connected in parallel, the combined resistance is lower. The torque speed characteristics of double squirrel cage motor for both the cages are shown in the figure below.
DFIG is similar to a wound rotor induc-tion machine IM and comprises a three-phase stator winding and a three-phase rotor winding. The latter is fed via slip rings. The voltage and torque equations of the DFIG in a stationary ref-erence frame are vri dt Sj S Sj j Sj 123,, 1 28

Jan 27, 2021 Thats fine for a Black Hawk, but untenable when it comes to two rotors on top of one another. That double-rotor setup also solves a problem that is
Double-rotor switched reluctance machine DRSRM is a new type of switched reluctance machine that is composed of two rotors and one stator integrated in one machine housing, which is potentially more compact, lower cost, and enables two mechanical outputs suitable for hybrid electric transmissions.
Double rotor mixers may be close to the same price as a single for the same volume. It is a function of drive costs. A double rotor mixer is closer to being square and this can give better angles and solve flowability problems with hoppers going to a single outlet. Also, there may be better angles for discharge and better access for cleaning.
