PRODUCT 2:
MULTI-SPEED AC MOTOR CONTROLLER
Indian Patent # 197983
European Patent # EP 1 081 842 B1
US Patent # 6,316,895 B1
This innovative concept is the
efficient and practically no maintenance solution for the conventional
multi-speed operation achieved in white goods using capacitor run single phase
motors with two capacitors for running
in two speeds.
Another advantage is other timing and
speed scheduling is taken care by the same Microcontroller, like in a washing machine,
thus eliminating the need for another controller and reducing the component
count.
The new system Comprises of:
·
Multi Speed Three Phase Motor
1.
Variable
Voltage Frequency
2.
No-Capacitor
No Torque pulsation
3.
Most
reliable Reduced Line/Ground Voltage
4.
Reduced
Motor Weight
·
Enhanced Micro controller for
1.
Real
time Switching of Inverter for Motor Control and Sine-PWM
2.
Motor
Reversal
3.
Total
system timing and Sequence Control
4.
Dynamic
Electric Breaking Possible
