What does timing do on a brushless motor?
What does timing do on a brushless motor?
Brushless motors react to increases and decreases in timing the same way as brushed motors, but most are a little less sensitive to changes. Increasing timing increases rpm and motor temps but decreases torque, efficiency and run time. Decreasing timing does, as expected, just the opposite.
How do I know if my brushless motor is faster?
Well, it is related to the power out from a motor. Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor.
What is ESC timing?
Motor timing is a settings on the ESC, it’s very important to motor efficiency, reliably, torque and RPM for multirotors. There are coils and magnets in a brushless motor. The goal of motor timing is to start switching the motor coil early, so we have the magnetic field ready at the right time.
What temperature should a brushless motor run?
160 is generally considered the maximum safe temp for BL motors, some brands can and do run hotter. Older LRP motors were fine at 180 and I’ve seen sensorless Castle motors run fine at 200. Performance gains over 150. Negligible at best in most cases.
How fast can brushless motors spin?
Brushless motors are capable of producing more torque and have a faster peak rotational speed compared to nitro- or gasoline-powered engines. Nitro engines peak at around 46,800 r/min and 2.2 kilowatts (3.0 hp), while a smaller brushless motor can reach 50,000 r/min and 3.7 kilowatts (5.0 hp).
What does Kv rating mean on brushless motor?
The Kv rating of a brushless motor is the ratio of the motor’s unloaded rpm to the peak voltage on the wires connected to the coils. A low Kv motor has more winds of thinner wire—it will carry more volts at fewer amps, produce higher torque, and swing a bigger prop.
Do brushless motors need to be broken in?
no such thing needed for a brushless motor. the break in was for brushed motors because it has… brushes that touch a moving armature. there is 0 contact in a brushless motor.
What is too hot for brushless motor?
Avoid raising the motor’s temperature past 170°F; any hotter, and you run the risk of damaging the rotor’s magnets. The good news is, most brushless power systems include thermal overload protection, which will shut the system down if the motor reaches critical temperature.
