MOTOR MITSUBISHI SP-QR Series Single phase induction motor, Split phase start type Open-protected type, IP20 Degrees of protection Horizontal foot mounted Output : 1/4~1/2HP Pole : 4 Voltage / Frequency : 220~230V 50Hz” Motor efficiency class IE1 “
Top class of light weighting and down sizing The best choice of employing steel frame and steel or aluminium bracket that enables light weighting and down sizing motor. High efficiency and high torque Accumulated techniques and CAE (Computer Aided Engineering) analysis that we found steel frame pass through magnetic field then can manufacture high power and save energy of motor. Powerful and smooth speed Due to high efficiency design focused on high acceleration torque and die-cast rotor of rather small moment of inertia enables smooth starting and stopping. Low vibration and low noise Our highly technology equipment, the ample rigidity, precise machining of each part and exact balancing of electrical design which makes MEATH motor have low vibration and low noise. Efficiency class guarantee The optimize electrical design and the material with low generation loss are used for core that make MITSUBISHI ELECTRIC AUTOMATION THAILAND are the first manufacturer in thailand who guarantee “IE1” efficiency class on single phase motor. High reliability Improve to highly reliable insulation system by using thermal class E to be standard. Longer life Based on selecting the proper bearing size and improving to have highly efficient cooling of bearing housing and steel frame which is greatly affect the longer bearing life. Best and reliable design of centrifugal switch The best design of centrifugal switch from MITSUBISHI ELECTRIC JAPAN that can manufacture in our highly technology equipment which can be reliable.
