Small capacity vector inverter dedicated motor

We offer 5.5 kW or higher SF-VR dedicated motors and do not offer small capacity (3.7 kW or lower) motors. If you need small capacity (1.5 kW to 3.7 kW), use... More Details >>

Comparison of noise with FR-A200

The setting ranges of the carrier frequency are:- FR-A200: 2 kHz to 14.5 kHz- FR-A200EXCELLENT: 0.7 kHz to 14.5 kHzThe range of the FR-A200E is extended to t... More Details >>

Do noise and leakage current increase?

During non-low-noise operation (initial setting) with the carrier frequency of 1 kHz, both noise and leakage current levels are almost same as the Z024 serie... More Details >>

Inverter current characteristics

In general, relationship between T (torque), K (constant), V (voltage), I (current), and F (frequency) is expressed as "T = K × (V/F) × I". Since (V/F) is co... More Details >>

Installing reactor for suppressing harmonics

You can connect multiple inverters to a single reactor. In this case, the load seems to be light from the reactor unless all of the inverters are rotating an... More Details >>
