Switched Reluctance Motors Drive for the
Electrical Traction in Shearer
Abstract—The paper presented the double Switched Reluctance motors parallel drive system
for the electrical traction in shearer. The system components, such as the Switched Reluctance
motor, the main circuit of the power converter and the controller, were described. The control
strategies of the closed-loop rotor speed control with PI algorithm and balancing the
distribution of the loads with fuzzy logic algorithm were given. The tests results were also
presented. It is shown that the relative deviation of the average DC supplied current of the
power converter in the Switched Reluctance motor 1 and in the Switched Reluctance motor 2
is within ±10%

I. INTRODUCTION
The underground surroundings of the coal mines are very execrable. One side, it is the
moist, high dust and inflammable surroundings. On the other side, the space of roadway is
limited since it is necessary to save the investment of exploiting coal mines so that it is
difficult to maintain the equipments. In the modern coal mines, the automatization equipments
could be used widely. The
faults of the automatization equipments could affect the production and the benefit of the
coal mines. The shearer is the mining equipment that coal could be cut from the coal wall.
The traditional shearer was driven by the hydrostatic transmission system. The fault ratio of
the hydrostatic transmission system is high since the fluid in hydrostatic transmission system
could be polluted easily. The faults of the hydrostatic transmission system could affect the
production and the benefit of the coal mines directly. The fault ratio of the motor drive system
is lower than th
