The rotational speed of the drum collector is an important parameter to determine the morphology of the nanofiber. Currently, many researchers are modifying single nozzle into multi-nozzle to obtain a wide range of materials. However, it requires more powerful syringe-pumps or increasing their number, leading to escalated cost. In addressing this issue, the sliding drum collector with an RPM counter is proposed as a solution. This apparatus uses a DC motor 775 and a stepper motor Nema17 as the driving device and an IR-sensor as the RPM counter. The RPM counter on this apparatus has also been calibrated and obtained an accuracy value of 97.87% and a precision value of 96.45%. The performance of the sliding drum collector has been validated. The sliding drum collectors have been proven to produce wider material with an area of (389 ± 8) cm2, (66 ± 18) cm2 larger than an ordinary drum collector.
