Synchronous Motors |
| |
 |
"MOTCO" make Synchronous Motors are constant speed machines i.e running at its synchronous speed. Synchronous motors are capable of being operated under a wide range of power factors, both lagging and leading. Hence, it can be used for power factor correction purposes, in addition to supplying torque to driven loads. |
Application areas :
1) Because of high efficiency and high speed synchronous motors (above 600 rpm) are well suited for loads where constant speed is required such centrifugal pumps, belt-driven reciprocating compressors, blowers, line shafts, rubber & paper mills etc.
2) Low speed synchronous motors
(below 600 rpm) are used for drives such as centrifugal and screw-type pumps, ball and tube mills, vacuum pumps, chippers and metal rolling mills etc.
3) Used for voltage regulation of Transmission lines.
DC motors requires a basic understanding of the design and operating characteristics of the various types available: the series motor, the shunt motor, and the compound motor. Each type has unique operating characteristics and applications.
 
| Technical Aspects : |
| 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 vaccum 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. |
