Frequency Drives

A.C. Adjustable Frequency Drive (AFD) Theory:

A.C. squirrel cage induction motors are typically characterized as constant speed when they are run from a 60Hz power source. If the source frequency can be adjusted, the motor speed and associated motor characteristics can be controlled to various levels of performance. Variable speed crane drives use existing A.C. power and convert it to D.C. via an electronic technique known as pulse width modulation (PWM). The Direct Current is then turned back into variable frequency alternating current (VFAC). With variable frequency A.C., the motor is now capable of performing to torque, efficiency or speed characteristics that are not typically associated with standard A.C. systems.

There are huge benefits in increased operating control and reduced maintenance costs by upgrading your crane controls to adjustable frequency drives. When switching to an AFD, conventional control systems such as resistor banks, timers and fluid couplings can be done away with. In addition, contactor arcing is eliminated and brake wear is reduced resulting in longer service life on your crane equipment. In place of these eleminated maintenance items frequency drives provide further reductions in wear through dynamic braking, controlled acceleration and deceleration, and motor over-current and over- temperature protection, which are inherent features of frequency drives.

AFD’s also allow more operating versatility! Their flexibliity in speed selection and slower speeds offer precise load positioning and reduced load swing.

pe_micro-speed_cx_variable_frequency_drive

Power Electronics Micro-Speed CX

Micro-Speed CX series A.C. variable speed drives are designed for traverse motions and for hoist with internal mechanical load brakes or self-locking worm gears.  The Micro-Speed CX is the only variable voltage, variable speed “scalar” drive designed specifically for the overhead crane industry.

High temperature ratings (60C/140F) and 300% current output make these heavy-duty and reliable units.  They feature Gang-Set instant programming, internal regeneration resistors built in (up to 5hp), dedicated brake control output relay, programmable auxiliary inputs, and rugged enclosures. Units are available with up to 5 speeds, including infinitely variable modes.

Select Micro-Speed CX for high horsepower, high current applications (available in up to 40hp models).  Micro-Speed MX models are available in models up to 300hp. Smart-Move offers many of the features of Micro-Speed CX for smaller, low horsepower applications.  All PE drives are designed, engineered, and manufactured in the USA.
