DYNAMOMETERS

 

DYNAMOMETERS

" MOTCO " make Dynamometers are available in various ranges and design features.(1 KW to 75 KW)

Dynamometers are used to measure HP and Torque of rotating Machines such as : electric-motors, engines, different types of pumps rotators etc.

TECHNICAL ASPECTS of "MOTCO" make DYNAMOMETERS :

DESIGN : Our Designs, parts & Dimensions are as per I.S.I Standards. Latest Innovations are  incorporated. Changes are made with times and also as per Customer demands.

FRAME & ENCLOSURE : Our Steel made Frames ensure greater strength & standard type production. Ventilation is provided by strong fan. In case of excess heat due to low speeds, Blower Mounting arrangement are provided for necessary Cooling.

WINDINGS : The Shunt Coils are wound in such a way with  Main Pole that, solid inter-pole & main-pole base would withstand any type of vibration. Coils made of copper conductors are insulated & then vacuum impregnated with high grade varnish ensuring resistance against acids, oil & moisture.

COMMUTATORS : Manufactured Cylindrically, with hard-drawn copper and V-Groove segments of high conductivity, insulated by a mica sheet in between. Complete commutator is baked for high temperature testing.

BRUSH BOX & BRUSHES : Brush Gear is made of strong, special design- but with simple construction- making it possible for shafts to rotate easily at low speeds with noise-free service. Provision for easy access to replace and adjust the brushes is provided. Brushes are of standard grades, ensuring sparkless commutation.

ARMATURE : Armatures are built of high quality Standard Steel Laminations, Securely insulated from each other and clamped together under high pressure ensuring low heating losses. Coils and wire-winding is strictly as per insulation class 'B'. Armature is tested for Dynamic Balancing. Resin Binding means full protection of Armature in all respects.

TESTING : Our all products are thoroughly  & vigorously tested on special Heavy Duty Test Bench and Dynamometer. All continuously rated Motors & Generators are tested on Full Load for more than Five Hours (HEAT RUN TEST) for temperature rises and the same are not permitted  to exceed values prescribed as per I.S. 4722. All windings are put to insulation test with lowest rate of 1.5 to 2 KV.


1)
Housing duly heat treated and precision machined.
2)
Shaft is made of alloy steel and is suitably heat treated, machined and precision ground to achieve optimum strength, rigidity and accuracy.
3)
Pre lubricated and sealed precision ball bearings for long maintenance free life.
4)
Silver graphite brushes which minimize voltage drop at varying loads and speeds.
5)
Brush holders ensure smooth movement of Brushes.
6)
Temperature Compensation can be provided to ensure extreme accuracy even with wide fluctuation in Ambient Temperature.
7)
Commutator built with electrolytic grade work hardened copper segments moulded and machined to close tolerances to achieve sparkless commutation and minimum wear. Use of mica insulation between segments ensures maximum dielectric strength and stability.
8)
Armature built with special silicon steel stampings and wound with polyester grade class "B" enameled Copper wire and vacuum impregnated for high electrical and mechanical strength. Leads are hot staked to commutator segments for excellent electrical contact and mechanical bonding.
9)
The Armature is dynamically balanced to ensure vibration free rotation, sparkles commutation and low ripple content.
