J j engineering works manufactures 3-phase induction motors. These 3-phase induction motors are modelled in a standard range, say the products in 2-pole [3000 rpm synchronous], 4-pole [1500 rpm synchronous s], 6-pole [1000 rpm synchronous] and 8-pole [750 rpm synchronous] configuration. They have output ranges of 0.09-22 kw and are available in iec frame sizes 63-180 [l and m] conforming to accepted standards. Design-specifications: robust cat frames and end covers, driving end shaft with tapped centre hole and motor enclosures and terminal box with ip 54 degree of protection. The motors are available in foot/flange and face mounting designs. Special attributes which can be added on request are: ±10% voltage variation, ±6% frequency variation, ambient temperatures, higher that 45°c, insulation class or h; motors with separate cooling arrangement [for inverter duty] ip 54 or 55 protection; motors for special applications like crane and hoist duty with special shaft dimensions, etc.; and motors with specific torque/speed features.
