Description

technical field [0001] The invention relates to a transmission conversion mechanism, in particular to a reciprocating mechanism driven by gravity. Background technique [0002] The transmission conversion mode of modern power mechanism is mostly carried out by means of frequency converter to control the motor. The frequency converter controls the speed of the motor and controls the steering of the motor, which makes the speed output of the motor to the transmission mechanism extremely flexible. However, the common frequency converter has insufficient voltage compensation for the motor when outputting low frequency, and the torque boost of the motor is not enough, resulting in a decrease in the output torque of the motor and unstable load capacity. Especially in the process of frequent start, stop, and reverse at low speeds, ordinary frequency converters do have shortcomings, and the mechanical transmission mechanism needs to be redesigned to achieve a more ideal transmission...

Problems solved by technology

However, the common frequency converter has insufficient voltage compensation for the motor when outputting low frequency, and the torque increase of the motor is not enough, resulting in a decrease in the output torque of the motor and unstable load capacity.

Especially in the process of frequent starting, stopping and reversing at low speeds, ordinary inverters do have shortcomings, and it is necessary to redesign the mechanical transmission mechanism to achieve a more ideal transmission.
