Frequently Asked Questions
What is a brushless DC motor?
A brushless DC motor also referred to as electronically commutated motors are a type of synchronous motor that is powered by a DC electric source by way of a integrated inverter. This inverter will produce an AC electric signal to drive the motor. Additional sensors will control the inverter output. Brushless motors are often referred to as stepper motors, however stepper motors are designed to be frequently stopped at predetermined intervals and angular positions.
Can a battery run a Brushless DC Motor?
Yes! With the use of a driver or controller.
When the load is increased, will the Brushless DC Motor slow down?
No in closed loop it the torque of the motor is strong enough, but always in open loop.
How do Brushless DC Motors Work?
A Brushless DC Motor, or BLDC Motor, is operated by means of an electronic six-step commutation system. Unlike its Brush DC Motor counterparts, the Brushless DC Motor does not contain any carbon brushes. Instead of brushes, the electromagnets within the motor remain stationary along with the armature, while the encased permanent magnets rotate, generating torque. The BLDC Motor is synchronous; both the stator and the magnetic field generate the same frequency, therefore avoiding any type of "slip" most induction motors exhibit.
Do Hall Sensors need to be used to drive a Brushless DC Motor?
No, Hall sensors are only needed for feedback systems requiring a Hall Effect Sensor. A Brushless Motor may be sensor less where the back EMF is used to run the motor.
Can different voltages be applied to my motor other than the specified voltage?
Yes, you can apply different voltages, although, you must keep in mind that there is a speed limit for the bearings. If you increase the voltage, the speed will increase. If you decrease the voltage then the speed will decrease. For example, if a Brushless DC Motor is rated to run at 3000 RPM no load with 36VDC, the motor will run 2000 RPM with24VDC. The maximum speed, torque, and power are directly proportional to the voltage.
What speed do your Brushless DC motors go up to?
Most are variable speed with ranges from 400-4000 rpm while some models can run as high as 10,000 rpm.
Will a Brushless DC Motor slow down when the load is increased?
In closed-loop control, the Brushless DC Motor will not slow down, as long at the torque of the motor is strong enough. However, it will always slow down with open-loop control.
