Electrical part
MC: With electrolytic start capacitor and centrifugal switch
BS: Same as above plus a run capacitor
Advantages :
MC : high starting torque
BS : high starting torque
power factor near 1
more compact and noiseless motor
Use : compressors, pistonpumps, kitchen machines, machine-tools, hoists, a.s.
Run capacitor start
Advantages :
low starting torque
slow and progressive start
power factor near 1
Use : machines starting with reduced load, e.g. : centrifugal pumps, fans, mixers, sawingmachines, doors, robots, etc.
