Can I use a VSD with multiple motors?

  The simple answer is yes. You can run multiple motors with a single VSD, provided they all need to run at the same speed. There are many advantages to this arrangement as a way of reducing system cost and complexity. Some factors need consideration when designing the system. VSD with multiple motors The main […]

Does Occam’s Razor apply to modern control solutions?

Some 800 years ago, English philosopher William of Ockham developed a principle giving precedence to simplicity. Called Occam’s Razor, his problem-solving principle is that in the event of two competing solutions, the simpler one is preferable. It is sometimes expressed as “Entities are not to be multiplied beyond necessity.” Putting this into a modern context, […]

Soft starter or VSD for controlling conveyor motors?

For most motor drive applications, the choice between VSDs and soft starters is clear cut. But for conveyor applications, either option may be suitable, and selection is a balance between price and performance. Soft starters Soft starters provide a slow ramp-up (soft start-up) of the motor to minimise mechanical shock and electrical peak demand. They […]

Importance of motor protection in modern industries

According to Schneider Electric, it is simple to underestimate the importance of electric motor protection in modern industries. Since their development 150 years ago, the design and performance of electric motors have undergone many refinements. But their fundamental function remains unchanged: they convert electrical energy into mechanical movement. Overall, electric motors provide the power to run […]

New Mitsubishi FX5U safety extension modules for PLC, simplify design.

  Mitsubishi Electric has strengthened its compact PLC series with the addition of two new FX5U safety extension modules. The modules allow users to create a compact, integrated safety system by connecting a safety extension module to a PLC. Developed and produced in conjunction with German safety maker SICK AG, the modules connect directly to FXU and […]
