ATS-40XM Silicon Steel Core Test System
In the field of motor industry, stator core testing is an important quality assurance measure, which can predict the reliability of the motor and subsequent operation and maintenance costs.
 
ATS-400M/401M Silicon Steel Core Test System is mainly used to measure the core loss of large motor (silicon steel) core. The no-load current and core loss are measured under the condition of power frequency. The device is equipped with infrared themometer, which can be used to detect the magnetic characteristics of silicon steel cores and local hot spots of cores, so as to achieve the purpose of product quality control.
 
The device can control and read the power supply by software on PC, and software has functions of automatic measurement, test data display in real time, save test results, save test plan and so on.

 Features                                             

► The system supports two measurement modes of single coil and double coils.
► The sample(core), magnetizing coil (N1), measurement coil (N2) together constitute a no-load transformer.
► The magnetizing coil loop is connected in series with the non-inductive resistance, and the magnetizing current is determined by measuring the voltage drop on the non-inductive resistance and get magnetic field strength, the locking of the peak of magnetic field is achieved through digital feedback.
► The magnetic induction intensity is obtained by digital integration of the voltage on the measuring coil, and the peak of magnetic induction is locked by digital feedback.
► It can measure the core loss of motor stator and display the excitation current, inductive voltage, core loss and frequency in real time.
► The temperature rise of the stator core under working magnetic induction and the local hot spot analysis can be detected by the infrared themometer.
