Description Of Brushless DC Motor Characteristic Curve

 

•The maximum of instaneeous torque line: the motor starting the maximum torque of motor , instantaneous impact load; beyond the torque value, over-current protection will lead to stop.

•Short-term running area: when t he motor at different speed, it can operate in a short time during this torque range, but after a long time it can cause heating of the motor, resulting motor break or drive overheat protection start, cause stopping working.

•Rated torque Rated torque of the motor line: at different speeds, the motor can run for a long time in this moment;

•In Continuous operation area: at different speed, the motor can operate continuous.

 


Product Features

 

■The Characteristics Of Brushless Motor Suitable For Speed Control Are Introduced

On brushless motor ,it is unecessarily using brush .commutator and any other mechanical contact. Brush motor need brush and commutato to running ,so it need to regular maintain. However, brushless motor used Hall 1C to detect the signal and used driving circuit of crystal catheter's ON/OFF. So it dispense with maintain.

 

■Stable Speed Control

Brushless DC motors compare the setting speed with the speed feedback signals from the motor at all times and adjust the motor's applied voltageFor this reason, even if the load changes, stable rotation is performed from low speed to high speed.Common inverter-controller three-phase induction motors do not have this type of feedback control and when the load changes, the speed can be affected. Brushless DC motors are recommended for applications that require the speed to be maintained regardless of the load fluctuation.

 

 

 

■Wide Speed Control Range (ZD is Currently the Rate Limiting to 2500RPM, This Drive Change can be Applied to the 4000RPM Motor)

The brushless DC motor has a broader speed control range compared to three-phase inverter driven motors. Unlike three-phase inverter driven motors, the torque at low speed isnot limited, so brushless DC motors are suited for applications that require constant.

■Saving Energy

DC Brushless motor used permanent magnets, it can reduce the secondary loss of rotor. So compared with adopts frequency conversion control of three-phase induction motor, the power reduced 23%. This is in favour of saving energy.

 

 

■Low Speed And High Torque Performance

DC brushless motor have a steady big torque when running at low speed.

■Thin, High Power

Brushless DC motors have a slim body and provide high power due to permanent magnets being used in the rotor. For example, the overall length is 75mm shorter and the output power is 1.3 times higher than that of three-phase induction motors with a frame size of 90mm. Using brushless DC motors can contribute to downsizing and space saving.

 

 

■Protection Function, Help To Protect The Safety Of The Equipment System

Due to the load of the overcurrent, undervoltage, open phase protection, for this reason can ensure the safety of equipment system.
