High Frequency Drives by Design

​

AV Series is a line of universal high frequency drives, suited for operation of a wide range of 3 phase AC motors, from standard “low speed” motors rated 50 or 60 Hz to high speed motors rated up to 6000 Hz (360,000 RPM for 2 pole design). ​

 

AV Series drives are differentiated from “standard” AC drives by the special attention which is given to specific needs of high frequency (low inductance) motors. The design was optimized around quality of voltage and current wave forms at any speed, low drive induced motor losses and vibration (bearing temperature and life) and control features which high speed motor applications typically require.​

​

High Quality Output for High Speed Motors

​

An active output filter for selective harmonic elimination significantly reduces motor losses (heat) and vibration, resulting in longer bearing and stator winding life. This approach results in better performance compared to most PAM and PWM type high frequency drives and is more universal than solutions with L-C filters.

Advanced Motor Protection

​

All three phase motor currents are continuously monitored by dedicated fast circuits for safe and expected values, for phase current differences (phase imbalance), for open connection in one phase and for short circuits.

 

If the insulation in a motor phase fails, AV Series drive will indicate in which phase is the problem without failing, which greatly facilitates machine/system troubleshooting. Load sensing measures real motor load and is fast and precise. Programmable timed-overload function permits transient overloads while thermally protecting the motor.

 

Two sensor inputs are available for monitoring of stator winding and bearing temperatures. Each input is programmable for use with PTC style, KTY 84, NC switch or PT 100 temperature sensors.

​​

Low System Costs

​​

No additional components are needed for most applications: Input EMI filters, output dV/dt filters and dynamic braking resistors are all included. Output filter reactors or output transformers are not required. Reduced spindle repair costs as a result of longer bearing and winding life. Low operating costs due to high system efficiency (low combined motor and drive losses).
