Synchronous Drive Systems (Synchronous Motors & Inverters)

What is a synchronous motor?

3-model series including a standard type, high-efficiency type and super high-efficiency type!

A synchronous motor is a motor that incorporates a permanent magnet in the rotor.
A synchronous motor differs from induction motors in that there is no flow of secondary current, because the magnetic flux is generated from the permanent magnet, thus resulting in a higher level of efficiency with significant loss reduction.
Furthermore, a synchronous motor (type with built-in permanent magnet) and FRENIC-MEGA (GX Series) inverter can be combined to create a "next-generation drive system" to replace the widely adopted conventional combination of an induction motor and inverter.
Always advancing... to a "future" with unimaginable possibilities

High-Efficiency & Energy-Saving

Standard type Motor efficiencySame level as IE3 (premium efficiency)!

High-efficiency type Motor efficiencySame level as IE4 (super premium efficiency)!

Super high-efficiency type Motor efficiencyHigher level than IE4 (super premium efficiency)!

*IE3 is based on the efficiency class regulations of IEC 60034-30, and IE4 on IEC 60034-31.

Comparison of Motor Efficiency Values

(Note1)
The induction motor efficiency values provided above are based on the values of JIS C 4210.
(Note2)
The standard type synchronous motor efficiency values provided above are based on the IE3 class values of the IEC 60034-30 regulations.
(Note3)
The high-efficiency type synchronous motor efficiency values provided above are based on the IE4 class values of the IEC 60034-31 regulations.

Further Energy Savings through Combined Operation!

A synchronous motor and FRENIC-MEGA GX Series inverter, equipped with our unique energy-saving control technology, can be combined to achieve further high-efficiency operation while reducing power loss.

Reference
It should be noted that for new facilities the initial investment costs are slightly higher (compared solely with the cost of an induction motor + inverter set), but the extremely low running cost of the combination allows the additional cost incurred when adopting it to be recovered in a short time.
