Electromagnets
-
The Lake Shore electromagnets (EM-V Series) produce magnetic fields with a variety of indexed air gap and pole cap configurations. The EM-V Series is ideally suited for integration into customer-designed magnetic test platforms for applications including magneto-optical studies, magnetic hysteresis studies, in-line annealing, Hall effect studies, susceptibility measurements, spin magnetic resonance demonstrations, and biological studies.

Powder Brake Dynamometers
PB Series
-
The Powder Brake Dynamometer (PB Series) contains, as its name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, thus producing a smooth braking torque through friction. They are ideal for applications operating in the low to middle speed range or when operating in the middle to high torque range. Like Hysteresis Brakes, Powder Brakes provide full torque at zero speed. Like the Eddy-Current Brake Dynamometers, the PB series are water-cooled, allowing for power ratings up to 48 kW. The PB Dynamometers have accuracy ratings of 0.3% to 0.5% full scale ( 2% for PB 2.7), depending on size and system configuration. Additional mounting possibilities include speed pickup and OEM version IS.

Transformer Performance Tester
6691
-
applying ±90V voltage on the winding of the transformer demagnetized and get the voltage value on the terminal and the current value in the winding to draw the hysteresis characteristic curve. This method can be used for linear quantitative analysis of residual magnetism in transformers, and fast demagnetization can be achieved by tracking hysteresis curves. The analyzer can measure magnetism residual rate before and after demagnetization.

Adaptive Inverse for Actuator Compensation Toolbox
AIFAC
-
Actuator nonlinearities such as dead-zone, backlash, and hysteresis are ubiquitous in mechanical connections, hydraulic servo-valves, electric servomotors, piezoelectric, pneumatic and magnetic actuators, and even appear in biomedical systems. The Adaptive Inverse For Actuator Compensation (AIFAC) Toolbox for Simulnk allows control system engineers to design high-performance adaptive controllers to compensate for uncertain or undesirable actuator dynamics that would otherwise adversely affect closed-loop control system performance.

Dial Weight Dynamometers
-
The most important characteristic of any measurement instrument is repeatability and accuracy. The Magtrol Dial Weight Dynamometer uses the combination of a Hysteresis Brake and gravity to insure constant, reliable results. The brake torque rise is directly proportional to applied current

Vibrating Sample Magnetometer
VSM
-
The VSM (also named M-H CURVE Hysteresis Graph TEST SYSTEM ) can be used for the measurement of the basic magnetic properties of the magnetic materials. Such as the Hysteresis loops of the materials, Magnetization curve, Warming Curve , Warming /Cooling curve, Cooling curve and the changes of the temperature as time goes away , then we will get some Magnetic parameters such as the Saturated strength of the magnetization, the left strength of the magnetization , Coercive force, the Max of Magnetic energy product,the Curie temperature and the Magnetic conductivity(the Initial Magnetic conductivity is included ). It can also measure the magnetic materials such as the powder, the particles, the films, the liquid and the massive.
