Brushless motor SX-1 Blue 34k RPM with RPM control - short shaft

The Solink SX-1 Blue is a brushless, DC electric motor.

Brushless DC motors have no brushes to get worn out, they represent a huge leap forward in technology. Brushless output significantly higher efficiency and performance, and have a lower susceptibility to mechanical wear than their brushed counterparts.

On the bottom of the motor there is a "L-H" switch which allows to change the RPM of the motor. In the "H" position the RPM is at the declared motor speed, in the "L" position the RPM is reduced by 20%.

The engine is designed to upgrade the weapon to a higher ROF.

WHAT ARE BRUSHLESS MOTORS?

The principle of the brushless DC motor was discovered in 1873 by Zénobe Gramme, and is therefore the oldest type of electric motor. A brushless DC motor consists of a stator and rotor and a commutator with brushes.

The brushless motor is the successor of the brushless DC motor The rotor is made up of permanent magnets (no need to apply an electric current to the rotor). The winding of the stator coils is switched by the control electronics so that a torque is continuously induced on the rotor, i.e. the DC supply is converted to AC by the ESC. This eliminates friction, sparking, excessive heat production and reduces wear on the carbon brushes and commutator. It outperforms the older brush motor in all parameters.

In brushless DC motors is the commutator is replaced by electronic FET switches. Unlike conventional AC synchronous motors, where commutation is provided by an external AC power supply (3 phases), winding commutation (change of current direction) is done electronically. Brushless motors are also referred to as BL (Brushless) or BLDC (Brushless DC).

ADVANTAGES OF BRUSHLESS MOTORS

• Higher torque to weight ratio
• Increased torque per watt of power input (increased efficiency)
• Increased reliability and lower maintenance requirements
• Reduced operational and mechanical noise
• Longer lifespan (no brush and commutator erosion)
• Elimination of ionizing sparks from the commutator (ESD)
• Near-elimination of electromagnetic interference (EMI)
• Easy to fit with no modification or additional wiring required
