    What could make a motor not achieve full RPM's?

    The motor speed could be low if the capacitor value has reduced by ageing. Please check the capacitor value by simply conneting it across 230/115V and measuring current though the capacitor. Use Voltage/Current (Xc) =1/w*C. Capacitors are known to lose value by upto 20% in 5 years and result in...
