Features of BEH Models （For ultra-high-speed control）

These dramatically improve the operating speed of clutches and brakes and achieve high-frequency operation and high-precision operation of machinery of various types.Installing a reverse excitation function in addition to overexcitation ensures that the fighting that can be a problem with large clutches and brakes does not occur. Optimal values have been preset for operation of Miki Pulley electromagnetic-actuated clutches and brakes, so complex adjustments are not required. Rigorous quiet designs mean that a strength of our electromagnetic clutches and brakes is a lack of whining.

[Characteristics]

Operating response

The circuit construction is completely contactless, and response from signal input to output to the electromagnetic-actuated clutch or brake is fast and stable. The operating speed of the electromagnetic clutch or brake is also increased to the limit speed by the overexcitation and reverse excitation functions. This is the top-of-the-line model for electromagnetic clutch/brake power supplies. It achieves ultra-high-speed control and high precision.

Noise During Operation

The BEH models are quiet power supplies.
Electromagnetic clutches and brakes normally produce howling sounds during operation. The quiet design of BEH models eliminates such sounds.

Output Control System

You can select either Stand-alone Mode, which controls stand-alone electromagnetic clutches and brakes independently, or Interlocked Mode, which is suited to combination control of electromagnetic clutches and brakes.
There is also a diverse array of other operating modes, such as current control mode and jog mode. These are compatible with a diversity of applications.

Supply Voltage Fluctuations and Output Voltage

BEH models control output voltage to be constant even with a certain amount of supply voltage fluctuation. This ensures stable output even in locations with a bad power supply environment. Variations in electromagnetic clutch/brake response disappear.
However, overly large voltage fluctuations will be sensed as abnormal voltages and set off an alarm. To ensure proper operation, keep supply voltage fluctuation to within a range of ± 10%.
