TODAY…MAXIMIZING η !
• Want to get more drive power with less cost?
• What are the limits of efficiency?
• Did you know that a 2007 Toyota Camry can out accelerate a 1968 Pontiac GTO?
EFFICIENCY!
MOTOR POWER• Motor Power is given by:
• Max power at
MOTOR EFFICIENCY• η=mechanical power / electrical power
MOTOR EFFICIENCY
SUMMARY OF ELECTRIC MOTORS
Servo Motor Advantages Disadvantages Applicable capacity
DC servo motor: (e.g., VR, stepper)
Easy to use, Low priced control device
Brush replacement. Has restrictions in respect of operating environment
0.1 - few 100 Watts
Brushless motor (PM synchronous) Synchronous motor (vector control)
No brush maintenance Excellent environment resistivity
Control device is expensive due to its complexity Detector is necessary
from few W to few kW
Induction motor (vector control)
Durable construction Complicated control system
More than few W
Stepping motor Open loop control, large static torque
Dropped out of step. Large weight/capacity ratio
Below few 10 W
THE POWER OF η• More Power• Less Money!
• Let’s Maximize η
η
WRAP-UP• The future…
• Research is the key to development
• Let’s see where efficiency can take us!
