The cylindrical motor 1 is provided with a frequency converter, the frequency converter comprises an energy feedback unit, and the electricity generated by the cylindrical motor 1 is conveyed to a user power grid again through the energy feedback unit for other equipment to use.
The utility model discloses a hoisting mechanism adopts the form of clutch to carry out the separation work through two motors, and another motor of a motor during operation is by clutch separation irrotational promptly. One motor is driven, the other motor is standby, and the standby motor does not influence the normal work of the driving motor. When the driving motor fails, the standby motor can be started, the heavy object is put down through the standby motor, and then the electric hoist is overhauled; on the other hand changes original conical motor into cylindrical motor, be equipped with the converter on cylindrical motor simultaneously, the converter includes the energy feedback unit, through the above-mentioned change, when this electric block hoisting mechanism action of actual measurement, only need cylindrical motor rated current can start (need motor 4.5 times rated current to start originally), when the heavy object descends, cylindrical motor is in the power generation state, the electricity that makes the motor send through the energy feedback unit is transported again and is supplied other equipment to use in the user's electric wire netting, the electric quantity has been saved, the availability factor of electric power has been improved.
The above description is directed to the specific embodiments of the present invention, but the present invention is not limited to the above description. Any equivalent modifications and substitutions to the present embodiments are within the scope of the present invention for those skilled in the art. Accordingly, variations and modifications in equivalents may be made without departing from the spirit and scope of the invention, which is intended to be covered by the following claims.
