Description
Introduction of Motor Stack Tester :
The Industry Standard Since 1989 – Gopal Electronics has the knowledge and experience of the magnetic measurement and Commercial Core Loss testing technology. Gopal Electronics make Core Loss Motor Stack Tester are use around the world by motor manufacturers for quality control during their production or reproduction process.
The Motor Stack Tester ST‐1000 is designed for determination of basic magnetic properties of Motor stack (ring, toroid or stamping) It can measure the Iron loss (Watt/kg), magnetizing force and permeability.
Motor Stack Tester Core Loss Theory
Not all power applied to an electric motor is converted to work. Principal sources of waste include winding (I²R) loss, friction, stray load loss and core loss in the stator, rotor or armature. Core loss is the excess energy required to magnetize the core and is due to eddy currents and hysteresis.
Increased loss results from physical damages or overheating of the core. Core Loss, dissipated heat, increases the operating temperature of the motor which causes more heat and can shorten the winding life. The core loss is considered the second leading cause or motor inefficiency behind only copper loss.
Your company should consider core loss testing because it is the only method of correctly determining if that motor operated at a rated efficiency after it is built.
Features of Motor Stack Tester :
1. Fully Automatic test method
2. Only one turn required to wind around the stack for measurement
3. Custom designs as per required core area to be tested
4. Core loss in watts/kg (lb) is automatically calculated based on core dimensions.
5. The entire test takes only about 2 minutes!
6. Industry Accepted Formulas for calculations of Core Volume and Core Loss
7. Reports can be generated by attached thermal printer
