VL - 8 IS - 1 SE - Research Article DO - UR - https://ph01.tci-thaijo.org/index.php/snru_journal/article/view/55340 SP - 163-169 AB - <span>This article presents an estimation of a rated motor for a multi-purpose shredding machine employed for <span>transforming twigs or weeds for agricultural purposes. A three-phase induction motor is used as a power source to<br /><span>substitute for a diesel engine which incurs higher operating costs. Also, a digital signal processing unit is used to <span>determine torque and power during experiment which can be calculated from current signal and voltage. A motor<br /><span>speed is measured by different types of sensors. The experimental results show that the estimation of power <span>consumption of the motor for a multi-purpose shredding machine based on this method provided similar values<br /><span>to the actual ones derived from torque sensors. Furthermore, this method is employed in order to determine <span>whether power consumption of the motor is suitable for shredding each type of material, and being appropriate<br /><span>selection of rated power of the motor that can help prevent unnecessary loss of power.</span></span></span></span></span></span></span></span><br /></span> ER -
