Abstract
A comparative analysis of sheep-shearing machines has been performed. Advantages and disadvantages of shearing machines with a single-phase commutator motor compared to a three-phase asynchronous electric motor with a short-circuited rotor are identified. An individual electric shearing unit with the improved converter and upgraded cutting machine with a vertical push mechanism is offered. This assembly equipment increases the efficiency of shearing the sheep due to the improved characteristics of the converter and the working parts of the shearing machine. The frequency converter has an energy saving function reducing the energy losses. The weight of the improved converter compared to the prototype is decreased by 2.1 kg. The vertical push mechanism gives a threefold reduction in the uneven pressing of the knife to the comb in a sharing machine. Comparative analysis of sheep-shearing machines has been performed.
