Robin Priestley Rockwell Automation. Up to 500 Horsepower. Comparison of mechanical capacity control and speed capacity control Flow changes linearly with speed Flow Rate 2 Flow Rate 1 x RPM 2 RPM 1 Head varies as the speed squared Lift.

Slip Ns Nb x 100 Ns Ns synchronous speed in RPM Nb base speed in RPM Sync. P of poles 1800 120604. As mentioned earlier most machines are driven by an electric motor.

The actual output speed of the rotor is related to the synchronous speed via the slip or percent slip. The ratio of static to friction head over the operating range influences the benefits achievable from variable speed drives see section 322 Figure 24. As shown below have universal product manuals shall be provided for parts listing.

Offering the largest application segments for the standard variable torque AC drive technology. Speed and slip Motor never runs at synchronous speed but lower base speed Difference is slip Typical slip is 3 1800 1750 RPM Calculate slip using the formula below. It has excellent static and dynamic performance and highly-precise torque speed and position control.

S N s - N N s eq. An electric ASD is an electrical system used to control motor speed. Speed Ns Ns 120 f P Ffreq.

The most efficient of these is pump speed con-trol. A comparison of mechanical and speed control for capacity reduction Figure 4 shows that variable speed is the most efficient means of capacity control. Variable frequency drives in.

Summit ESP ACS-15 Active Front End Variable Speed Drives Summit ESP ACS -15 drives provide quick response and adaptability to dynamic operating conditions attendant with your application.

Typically a Variable Speed Drive VSD is a system that uses an external signal to control the rotational speed and torque of an AC induction motor by adjusting the frequency of the power. By varying the speed of its drive motor as air demand decreases the VSD lowers the delivered air flow as well as the electrical power consumption in a largely linear fashion. A variable speed drive VSD also known as a frequency converter adjustable speed drive or inverter is an electronic device that controls the characteristics of a motors electrical supply.

Huge energy savings potential operating centrifugal fans pumps and compressors Vary frequency of electrical supply to an induction motor to vary the motor speed. Variable Speed Drives Control valves change flow by changing the system resistance restriction area to flow.
