Wound-Rotor Motors — High Torque and Adjustable Speed

Wound-rotor motors deliver speed control of heavy and high-torque loads.What's special about the wound-rotor motor? This type of 3-phase induction motor has high starting torque, which makes it ideal for applications where standard NEMA design motors fall short. The wound-rotor motor is particularly effective in applications where using a squirrel-cage motor may result in a starting current that's

Three Phase Induction Motor Starting Methods Starting

Metallic Resistor Starters. Liquid Resistor Starters. Auto Transformer. Soft Start. Secondary Resistance. When a three-phase squirrel cage induction motor is connected directly to the supply, it will draw a large starting current. This current, which usually lasts only a second or two, can be up to seven times the motor’s full-load current.

Liquid starter Electric motors & generators engineering

Jul 31, 2003· In an old motor shop we had a liquid starter that we used to load test our generators.We used a brine solusion in it and controlled the resistance by moving 3 rods in and out of the brine.We didn't have to be very concerned about the Conductivity of the solution,because our primary need was to creat a measurable load.
