Brushless motor Professional PLUS 40k RPM with RPM control - short shaft

The SOLINK PROFESSIONAL Plus motor is a brushless DC electric motor.

Brushless motors have no brushes to wear out and represent a huge technological leap forward. They have significantly higher efficiency and performance and are less prone to mechanical wear than their brushed counterparts.

VERSION

• PROFESSIONAL PLUS 40k, short shaft

ADVANTAGES

• Versatile RPM Modes: Easily switch between High-Low RPM mode (Low RPM is around 20%RPM less than its high RPM mode) to customize your motor’s performance, ensuring a smoother and more enjoyable experience every time.
• Unidirectional Bearing Design: Innovative unidirectional bearing design prevents reverse rotation, eliminating the need for an anti-reversal latch. Say goodbye to annoying latch noise and hello to smoother, quieter gear rotation.
• Excellent Efficiency: The Solink brushless motor features exceptional efficiency. Even after firing 200 BBs, it operates at a temperature approximately 10 degrees lower than most brushed motors. This means the magnets inside the motor will last much longer than in brushed motors before a drop in torque occurs.
• Extended Lifespan: Designed with a stationary coil, the Solink brushless motor is built to last. This design significantly extends its lifespan compared to traditional brushed motors.
• Powerful Torque: Thanks to its high torque, the Solink brushless motor effortlessly handles strong springs, making it a robust and reliable choice for demanding builds.
• CNC Shell and D-Type Pinion: The CNC shell significantly aids in heat dissipation, while the D-type pinion design is compatible with most current gear brands.

WHAT ARE BRUSHLESS MOTORS?

The principle of the brushed DC motor was discovered in 1873 by Zénobe Gramme, making it the oldest type of electric motor. A brushed DC motor consists of a stator, a rotor (armature), and a commutator (rotary switch) with brushes (carbon brushes).

A brushless motor is the successor to the brushed DC motor—the rotor is made of permanent magnets (no need to supply electrical current to the rotor). The stator coil windings are switched by control electronics to constantly generate torque on the rotor, meaning the DC power supply is converted into alternating current by an electronic ESC (Electronic Speed Controller) unit. This eliminates friction, sparking, and excessive heat generation, while reducing the wear found on carbon brushes and commutators. It outperforms the older brushed motor in every single parameter.

Sometimes brushless motors are referred to as AC motors, but technically it is a DC motor where the commutator is replaced by electronic FET switches. Unlike classic AC synchronous motors, where commutation is provided by an external AC network (3 phases), winding commutation (change of current direction) is performed electronically. Brushless motors are also designated as BL (Brushless) or BLDC (Brushless DC).

ADVANTAGES OF BRUSHLESS MOTORS

• Higher torque-to-weight ratio.
• Higher torque per watt of power input (higher efficiency).
• Higher reliability and lower maintenance requirements.
• Lower operational and mechanical noise.
• Longer lifespan (no wear on brushes and commutator).
• Elimination of sparking from the commutator (ESD).
• Near-total elimination of electromagnetic interference (EMI).
• Easy installation without the need for modifications or additional wiring.
