MOTOR MITSUBISHI SI-K Series (Repulsion start type, IP44)
Horizontal type Single phase induction motor totally enclosed type, IP44 Degrees of protection
SI-K 1/2HP 4P, SI-K 1HP 4P, SI-K 1 3/4HP 4P
The variety of type of Single Phase Motor based on JIS (Japanese Industrial Standard) and IEC (International Electrotechnical Commission). And being positively advanced under technological assistance contract with MITSUBISHI ELECTRIC JAPAN which have an experience for manufacturing motor since 1907.
Top class of light weighting and down sizing
The best choice of employing steel frame and steel or aluminium bracket (excluding SI-K Type) 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.
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.
