Variable frequency drive manufacturers offer products to be used with electric motors. A variable frequency drive is also known as a VFD, variable speed drive, adjustable speed drive, electronic motor controller, or an inverter. Every VFD is unique with its own component characteristics; so, how each VFD works is dependent upon components within the VFD. Most VFDs integrate a solid state electronics controller, consisting of a bridge rectifier, a converter, and an inverter module. Properly applied variable frequency drives can significantly reduce production operating costs.

Variable Frequency Drive Manufacturers: Lenze Americas
Lenze Americas drives are mainly used for any application that does not require speed feedback. Lenze drives are built in America and are an inexpensive solution for food processing, packaging machinery, materials handling, conveying systems, and HVAC systems. The SMV series of Lenze drives range from IP31 (NEMA 1) and IP65 (NEMA 4/NEMA 4X) in power ratings from 120V to 240V through 480V and 600V. The SMV series of Lenze drives offer sophisticated auto-tuning, fast dynamic toque response with impressive low-speed operation all from a compact and simple to use package. The SMV range is designed for motor applications where dynamic speed and torque control is demanded, making the units ideal for conveyors, food production lines, packaging equipment plus fan & pump systems.The SMV series of Lenze drives use a price leadership tradition in the highly competitive AC drive market. With the benefit of a two year warranty, the SMV series of Lenze drives offer performance and flexibility make it an attractive solution for a broad range of applications.
The SMV series of Lenze drives use price leadership in delivering unparalleled performance and simplicity. The SMV series of Lenze drives is the right choice for performance, power, packaging and intuitive programming. The Lenze SMV series of Lenze drives use an Electronic Programming Module (EPM) for programming. The Lenze EPM makes for ease of hassle-free reconfiguration within each parameter or resetting the drive to factory or user default settings. When drive reset is necessary, reset to factory default or customer settings in seconds with the EPM. When the EPM equipped drive is used on a line containing multiple drives with the identical setup, it takes just minutes to program the entire line. The EPM’s can be replaced with or without power connected. When a drive must be replaced, the parameter configuration is not lost, simply plug in the pre-programmed EPM. Lenze is one of several variable frequency drive manufacturers offered by Precision Electric.
Variable Frequency Drive Manufacturers: Hitachi
Hitachi AC Variable frequency drives are utilized for an array of applications. Hitachi drives are equipped with several advanced features and deliver unprecedented performance and reliability. Hitachi drives are a result of high degree of commonality between models and user friendly configuration software – making them easy to install, program and maintain. The SJ700D Hitachi inverter is designed with more capabilities and functions of its predecessor, the Hitachi SJ700B Series. SJ700D inverters come with improved sensorless vector (SLV) control algorithm, which allows the SJ700D Series to develop 150% torque at 0.5 Hz, ideal for a wide range of applications. Another key upgrade in the SJ700D Series is the addition of Hitachi’s EzSQ (Easy Sequence) built-in programming function, which provides the functionality of a PLC built into the inverter.
SJ700D inverters offer built in programming functions. Sequence operations are used by downloading programs created with Hitachi’s EzSQ software and then transferred to the Hitachi inverters. Operation of SJ700D inverters can be tailored to meet changing process requirements and SJ700D inverters can replace separate PLC’s in some cases to simplify or eliminate external hardware, which reduces cost and increases performance. SJ700D Hitachi inverters through 150kW have a built-in EMC filter to reduce electromagnetic noise, cost and space. SJ700D inverters have a lifetime warning function to allow preventive maintenance before a failure occurs.
