Product description
For today's regulated electric lifts and hoists and hoist drives, the basic requirements are high precision and smooth speed control, provided good quality of transients. DC motors in many cases to meet these requirements, but their use is often undesirable because of the mechanical switch that requires constant maintenance.
Induction motors received in the industry is very widespread use due to a number of significant advantages over other types of engines. The induction motor is simple and reliable in operation, much smaller in size and weight of the DC motors.
One way of controlling the speed of asynchronous motors, which now is widely used among foreign manufacturers - the conversion rate.
This project uses the inverter MIDIMASTER VECTOR MDV 1100/3 company SIEMENS, which allows you to achieve the highest possible performance control of AC motors.
