Dc Drives - Its Engineering and Integration

With the expertise and knowledge of a very experienced team of engineers and technical staff, clear associates are able to supply solutions for either existing drive problems or new applications. Find below a list of solutions that may be helpful to your business:

  • Engineered cabinet cooling theory for any environment. Today's Dc drives are more compact and can be settled in smaller enclosures only if the strict cooling is applied.
  • Power and harmonics issues can be addressed and corrected through the use of isolation transformers, reactors and filter packages.
  • Communication Systems for developed Modbus, Profibus and Data HighWay linking complicated devices such as power administration and Hmi/Plc systems.
  • Customizing operate and analog circuitry to be integrated with existing engineered specifications.
  • Sizing a Dc drive to a target horsepower, current and voltage required.
  • Peer to Peer and Master/Slave drive configurations for Follower and High Horsepower applications.
  • Operator consoles / Door mounted pilot and metering devices.

Mcc and Switchgear facility type practice packaging for growing demands within the industry. Because of their favourable cost, ease of use, simplicity, and reliability, Dc drives has been fulfilling an foremost role within commercial applications. Dc drives are generally connected with a silicon controller rectifier (Scr) power conversion. The Scr, (also called the thyristor) converts the fixed voltage alternating current (Ac) of the power source to an adjustable voltage, controlled direct current (Dc) yield which is applied to the armature of a Dc motor.

Through the use of phase angle control, Scr's are capable of providing ontrollable power output. This term refers to the firing angle of the Scr (a point in time where the Scr is triggered into conduction). The Scr is thus synchronized with the phase rotation of the Ac power source. If the gismo is triggered early in half cycle, maximum power is delivered to the Dc motor, whereas late triggering in the half cycle provides minimum power. The consequent can be compared to a very high speed switch, capable of being turned on and conducted off at an infinite estimate of points within each half cycle. This happens at a rate of 60 times a second on a 60 Hz line, to deliver a strict estimate of power to the Dc motor. The form of power operate is very productive finding as a very small estimate of triggering energy can enable the Scr (Silicon Controlled Rectifier) to operate a great deal of yield power.
