Brushless DC motors

Brushless DC motors from the GREEN LINE range are available in 5 sizes with torque from 0.22 Nm to 2.1Nm and they are supplied with external driver.
The advantages of using brushless motors instead of traditional DC brushed motors are the following:

Longer life time
Higher efficiency
Electronic commutation and control of the motor via digital sensors (encoder, resolver etc.)
Wide speed range
Maintenance free

GREEN LINE motors have a compact design and thanks to low inertia they have high performances and are a low cost solution already including Hall sensors, as opposed to an encoder or resolver.
The 3 phase windings of the motor have a low voltage of 24/36/48 V and so these motors are safer to use when a machine operator has direct contact with them.

Indicates the degree of mechanical insulation of the motor body.

1st figure indicating level of protection against the penetration of
solid bodies.
2nd figure: indicating degree to which the motor is waterproof.

IEC duty cycle ratings
S1	Continuous duty. The motor works at a constant load for enough time to reach temperature equilibrium
S2	Short time duty. The motor works at a constant load, but not long enough to reach temperature equilibrium, and the rest periods are long enough for the motor to reach ambient temperature.
S3	Intermittent periodic duty. Sequential, identical run and rest cycles with constant load. Temperature equilibrium is never reached. Starting current has little effect on temperature rise.

Legend

With a brushless motor, the rotational speed is a linear function of the torque. In the same way, the absorbed current is also a linear function of the torque. Speed and current change a lot against applied torque.

grafico-motori-brushless

The output power is calculated using the formula:

grafico-motori-brushless-2

Since the supply voltage is constant, whereas the current increases in a linear manner as the torque increases, the absorbed power trend is a straight line going up. Efficiency is shown from the ratio between the output power and the absorbed power.
