Motor Control Resistors
Buy various high quality Motor Control Resistors online globally in various models having high efficiency and longer service life as per changing market demands

We are offering Starting/Motor Control Resistors. For starting / Speed Control of A.C or D.C. Motors, resistors are manufactured as per customers requirement at specified starting torque or for limiting initial inrush current to an acceptable value. Mainly these are used for cranes. Rating can be 2 minute, 5 minute, 10 minute, continuous or intermittent. Material of resistor is normally Stainless steel AISI-304, AISI -410 or AISI 430 or FeCrAl-AISI-406.

Standards Followed:

IPSS-1-10-002-82 with amendment no.1 and BS 587 for starting / speed control resistor.
IS 2147 & IS 12063 of 1987 for degree of protection for enclosure.
IS 5 for paint shade.
Any other standard as required can also be followed.

TESTS:-

(A). ROUTINE TESTS: - FOLLOWING TESTS WILL BE CONDUCTED.

Visual and Dimensional
Insulation resistance value measurement by using 500V megger before and after dielectric test.
Resistance value measurement with Â± 10 % tolerance.
H.V. Test of twice the rated voltage +1000 volts for voltage class below 660 volts.

TYPE TESTS:-

Temperature rise test i.e., Heat run test if required will be conducted by passing equivalent / rated current for rated / equivalent time keeping IT Constant through a part of Resistor.
