Magnetek Has Been Building Elevator Drives Since 197611/18/2016Magnetek has been building AC and DC drives for the elevator business since 1976. Since that time they have produced many different models for the elevator industry that is widely used by all of the major elevator manufacturers including Otis Elevator Company, Schindler Elevator Corporation, Dover Elevator, Inc., ThyssenKrupp Elevator and other manufacturers as well. From the mid 1970’s, throughout the 1980’s Magnetek has produced a number of DC drives and later AC drives including the 44XL Machine Tool AC drive, 3400 series, 3212 series. During the 1990’s Magnetek revolutionized the elevator industry with the DSD 312 and DSD 412 DC drives. At the same time, the company released the GPD 503 standard volts / frequency drive and the VCD 703 Closed loop vector AC drives to be used on elevator applications, demonstrating that the AC drive is a good choice to use be used by elevator manufacturers.In 1998, the Magnetek HPV 900 AC vector drive was designed and introduced specifically for high performance elevator applications. The HPV 900 and HPV 900 Series 2 released in 2010 once again revolutionized the elevator industry as an energy efficient solution for both new installations and modernization projects of older systems. Designed with a 250% high capacity overload, there is no need to oversize to get the proper operation needed. The internal braking IGBT, relieves the need for external braking transistors. The cooling fans installed only run while the drive in operation reducing the wear and extending the operational lifecycle. The drive has a unique speed regulator for improved ride quality with smooth acceleration and deceleration, and greater landing accuracy.The set-up for the HPV 900 is easy since the parameters are laid out in elevator industry terminology. There is no need for a mechanical disconnect to tune critical motor parameters. Parameters can be uploaded or downloaded via software that communicates with the drive. Parameters can also be entered and / or changed by the user via a digital operator keypad. The encoder can be aligned to the motor without any sort of mechanical disconnect. Models in the 200 / 240 VAC class of drives range from 7.5 horsepower to 40 horsepower. Models in the 380 / 480 VAC class of drives range from 7.5 horsepower to 75 horsepower. Precision Electronic Services Inc., has many years of experience repairing the Magnetek HPV 900 drives. The most prominent issues that we have dealt with are blown semiconductor fuses, blown IGBT modules, logic faults, power supply failures, overheating issues, and ground faults. The issues with the blown fuses, bad transistor modules, and ground faults usually are a result of the IGBT modules being bad, either open or shorted. Overheating, can be as simple as clogged or inoperative fans or can be a bad temperature sensing circuit. If the drive is dead, the problem may be a bad power supply. And a logic fault is usually an indication of a bad control board. This of course is just a sampling of the symptoms that we have seen, and Precision Electronic Services has the experience and expertise to repair any and all of these issues.
