Compact, Energy-Saving, Low Noise Brushless Motor 750 W

The brushless motor 750 W (1 HP) type uses a PM motor with a permanent magnet in the rotor. When combined with an inverter, speed control range of 300~4000 r/min is possible. It is smaller and lighter than a three-phase AC motor, reducing the burden on assembly workers. In addition, achieves an efficiency level IE5, contributing to reduced electricity costs and CO₂ emissions.

Significantly reduced motor size
Contributes to making equipment more compact

Achieved IE5 level
Reduced electricity costs

Fanless design reduces noise level
In addition, no scattering of dust and other particles.

Smaller and More Lightweight Compared to Three-phase AC Motors With the Same Output Power

Brushless motors use permanent magnets in the rotor, making them highly efficient, compact, and lightweight.
In addition, the fanless structure has been achieved due to its high efficiency and low heat generation. It contributes to reducing equipment size and reducing the burden on workers.

Fanless and Low Noise

Brushless motors have the fanless structure due to its high efficiency and low heat generation. The noise level is reduced by approximately 20 dB when compared to a three-phase AC motor with fan.

Measurement Conditions
・No load
・Speed: 1500 r/min
・Measured at position 15 cm from the back of the motor

Reduces the Scattering of Dust and Other Particles Because of Fanless.

In the case of a motor with a fan, the cooling fan generates wind, which may scatter dust and other particles in the surrounding area.
Brushless motors are no risk of dust dispersal because of fanless.

Operates in Combination With an Inverter

Brushless motors are three-phase motors and can be controlled in combination with an inverter.

Note

Combinable inverters are inverters that can be combined with PM motors.

Connecting Brushless Motor 750 W With Inverters From Other Manufacturers
