Textile Motors, Ring Frame

JSL Industries offers a range of textile motors. These are specially designed to cater to a wide range of torque characteristics during starting, running, reversing and stopping of textile machinery. The `Jyoti’ range of textile motors embraces practically all textile machinery drives and is suitable for operation on 415 Volts ±10% supply with IP55 protection and F class of insulation with temperature rise limited to 'B'. The range comprises motors meeting requirements of textile processes such as fibre preparation; carding; weaving; combing and drawing; spinning and doubling. Ring frame motors (with smooth acceleration clean air flow arrangement): the most essential requirement of the ring frame drive is smooth acceleration which will help in minimising the breakage of yarn and at the same time maintaining the yarn tension at desirable level. 'Jyoti' ring frame motors are designed to meet these requirements. These motors are totally enclosed fan-cooled type. Fan shelter is specially designed to minimise the blockage due to cotton fluff and to ensure proper cooling of the motor. Terminal box is provided either on LHS or RHS looking from shaft-end as per customers' requirements. Motors with terminal box on top can also be supplied against specific requirement in case of spinning frame narrow width having limited space. These motors are available in a wide range of standard output ratings, in the synchronous speed of 1500 RPM. Construction features: the finned construction of stator cast iron frame offers optimum cooling characteristics; stacks are made of low loss silicon-steel stampings to reduce iron losses; insulation is class 'B' and temperature rise is limited to 80°C over ambient of 40°C as per IS:325; modified polyester enamelled winding wires as per IS:13730 (Part-III) are used; rotor stampings are stacked with pressure and then die cast with EC grade aluminium, shrink fitted on the shaft; and all motors are tested in the course of manufacture and before despatch in accordance with IS:325 and IS:2972.
