Abstract

This article presents an estimation of a rated motor for a multi-purpose shredding machine employed for transforming twigs or weeds for agricultural purposes. A three-phase induction motor is used as a power source to
substitute for a diesel engine which incurs higher operating costs. Also, a digital signal processing unit is used to determine torque and power during experiment which can be calculated from current signal and voltage. A motor
speed is measured by different types of sensors. The experimental results show that the estimation of power consumption of the motor for a multi-purpose shredding machine based on this method provided similar values
to the actual ones derived from torque sensors. Furthermore, this method is employed in order to determine whether power consumption of the motor is suitable for shredding each type of material, and being appropriate
selection of rated power of the motor that can help prevent unnecessary loss of power.
