Description
HIGHLY EFFICIENT, DURABLE AND RELIABLE
The constant contact of the brushes with the power terminals of a brushed motor is necessary for it to maintain its rotation. However, the friction that this creates means that a huge portion of the energy generated by the rotational motion is wasted as heat. Generally, the efficiency of brushed motors is limited within the range of 75% to 80%.
Brushed motors are notorious for having parts that get worn out after a while, requiring frequent dismantling and parts replacement. This is because the brushes of the commutator need to maintain almost constant contact with the terminals of the power source, even as the commutator rotates rapidly. When brushes get worn out and can no longer maintain contact, a brushed DC motor basically becomes useless.
This is less of a problem with brushless motors. In fact, there is essentially no contact between the rotor and stator of a brushless motor, so wear and tear are greatly reduced.
The Warhead BLACK motor is designed to be a cheaper alternative to its older broth the CNC black version. It is available in FOUR different speeds in both long and short shaft variants. The motor is fully compatible with a host of ETU and Mosfets including brands such as Jeftron, Gate and Perun.
Three different speeds available in Short and Long Shaft:
- 20K RPM AT 7.4V / 52K RPM AT 11.V
- 25K RPM AT 7.4V / 36K RPM AT 11.1V
- 35K RPM AT 7.4V / 30K RPM AT 11.1V
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.
Brushless motors offer several other advantages, including;
- 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)
