    摘要: A method for energy storage and recovery for load hoisting equipment driven by an inverter controlled first induction motor and having a second inverter controlling a second induction motor which drives a flywheel whereby, utilizing rest power such as reverse power from the first induction motor when lowering a load and unused power at small load or idle to accelerate rotation of a flywheel, whereby energy is stored, and the system is reversed when a load is lifted and power is consumed whereby the flywheel causes the second motor to generate power and deliver it to the first motor.
