Moving more than motors
Moeller offers a complete range of core drive products, from classic electromechanical contactors/switchgear up to innovative control devices for individual and economic solutions with machines and systems. A functionally stepped range matched to the varying requirements of different areas of application are available here.
The Moeller drive engineering packageThe three-phase motor
The three-phase motor is the most important and widespread electrical motor world-wide. It is exemplified by its robust construction, economically-priced design and high degree of protection. The resulting world-wide areas of application demand economic drive engineering concepts: From the simple motor start up to speed adjustment and control.
The following engineering solutions are generally used:
Soft starter/DS4 semiconductor contactors
 |
A soft and smooth motor start is enabled by the electronic soft starter.
It provides stepless control of the of the three-phase motor supply voltage in the start phase. The motor torque is matched to the load-performance of the machine load and provides smooth acceleration. Mechanical stresses and motor current peaks are avoided. The classic star-delta function can be simply replaced.
DS4 semiconductor contactors, depending on the version, can be used for motor loads (as soft starters) or non-motor loads (as semiconductor contactors). |
Soft starter DM4
 |
Top-quality soft starters such as the DM4 series can be individually matched to the requirements of the respective applications, and offer soft starting in its most comfortable form. A specific motor current reduction in the start phase and an application specific parameter definition ensure optimum matching to the characteristics of the three-phase drive. The DM4 can be used in the In Delta and In Line configurations.. The highest level of operating comfort, optional communication modules and motor protection functions which are already integrated, assure simple and safe handling of the drive. Soft starter DM4 |
Frequency inverters DV51, DV6/DF51, DF6
Frequency inverters convert the constant voltage and frequency of the mains supply to a DC voltage The frequency inverter generates a new three-phase supply with a variable voltage and frequency for the three-phase motor from this DC voltage.
This allows optimum matching of the speed or torque of the three-phase motor to suit the process. A wide area of application is offered by the DF51/DF6 series with its integrated V/f control. Frequency inverters DV51/DV6 additionally feature sensorless vector control (SLV) and vector control for example, for frequency and torque control on drives with a very high dynamic response and load demands. Optional communication modules enable integration in industrial networks.The "Drives-Soft" parameter definition software offers an efficient tool for the device series DF51, DV51, DF6 and DV6.
