RE: Can you run Brushless on NiMH packs? Sure it would, but a 9000kv motor isn’t even realistic just like a 4 turn brushed one isn’t. It’s a known fact hat if you want to go fast it’s better to run a lower kv motor with more voltage.
Can I connect a brushless motor directly to battery?
No, it’s not possible to drive a BLDC (or 3-phase) motor from DC without conversion. In order to create torque and rotation, a rotating magnetic field is needed. That can be created using AC or switching the coils periodically with a commutator or with an ESC.
Do brushless motors require LiPo batteries?
1.Do brushless motors require LiPo batteries? No. Atleast, you don’t have to use LiPo batteries with your brushless motor, but the merits involved when using one far outweigh those of any other battery.
Are NiMH batteries good for RC cars?
Yes, you can use NiMH batteries instead of NiCD batteries for your RC car. The cells of NiMH batteries will not cause any damage to your RC car because they have the same voltage as NiCD batteries. However, you have to use the right charger for the NiMH battery and not a NiCD charger for it.
Which battery is used for brushless motor?
LiPo batteries are well suited to this type of an operation because they can support varied discharge capacities. They are also much lighter thanks to the higher charge density. 2.
Can you run a brushless motor without an ESC?
You can’t even run a brushless DC motor without the ESC, let alone control it. The ESC, which actually is an inverter converting DC into three phase AC, is a necessary part of the motor.
How do you control the speed of a brushless motor?
An ESC or an Electronic Speed Controller controls the brushless motor movement or speed by activating the appropriate MOSFETs to create the rotating magnetic field so that the motor rotates. The higher the frequency or the quicker the ESC goes through the 6 intervals, the higher the speed of the motor will be.
What’s the difference between LiPo and NiMH?
The biggest difference between NiMH and LiPo batteries is the chemical properties that enable the charging of the batteries. NiMH (Nickel-metal hybrid) uses nickel-based technology and LiPo (Lithium Polymer) batteries use a lithium-ion technology.Both battery types must be disposed of properly as hazardous waste.
What is ESC for 3S LiPo?
Go with the MMP esc. Brushed or brushless, 6s capable, plenty of power. Mamba Monster 2 and new Sidewinder 8th will handle 3S LiPo, high power motors, run brushless and brushed, and are waterproof. So far I have not seen the Sidewinder 8th available standalone (without the motor).
Is LiPo faster than NiMH?
The main attractions to LiPo batteries are more speed, more “punch” off the line and more consistent power during the duration of the run compared to NiMH batteries.
Can I use a higher mAh battery in my RC car?
RC Newbie. Edough13 said: No a bigger battery (more mAh) won’t make it go faster unless it’s more cells. Guessing it’s supposed to run on 2s, so using a 3s battery yes would make it go faster but also possibly damage your ESC and motor.
Is 2s LiPo faster than NiMH?
A lipo pack’s ability to sustain a higher voltage than a nimh also means that you can gear up for better speed, and due to lighter weight, still not over-strain the motor with amp draw.
Can I use a lithium battery with a brushless motor?
BLDC motors powered by Li-ion batteries can exploit the new class of bridge drivers to further enhance battery life, longevity, and high reliability in battery-powered tools, portable medical equipment, and home-automation applications.
What batteries do drones use?
5 kWh Lithium-Ion Battery Pack for Drones and Robotics
The most commonly-used battery technologies in unmanned systems are lithium-based, as they have a higher energy density than the older nickel-based technologies so they can provide more useful power per unit weight.
Why are there 3 wires on a brushless motor?
The three wires give the brushless motors more pulling power. Understanding this helps understand stepper motors below. The two wires of the brushed dc motor can be thought of as forward and reverse. The three wires of brushless can be thought of as 1, 2 and 3.
Is a higher kV motor faster?
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.
How can I test my brushless motor without ESC?
You can certainly check brushless motor without ESC.
Here’s my trick…
- Disconnect motor from ESC just to be safe but not necessary.
- Short any 2 motor wires and spin rotor head by hand.
- Compare mechanical resistance without shorting the wires.
- Repeat with the other 2 combos of shorting 2 wires.
Are brushless motor waterproof?
The truth is brushless motors are water resistant however they are not really waterproof. Water is never pure in a lake or puddle or even rain. Small particles will find there way in to the bearings on a brushless motor delivered right from the water itself. Over time this is what can destroy the bearings.
Is brushless motor 3-phase?
A brushless DC (BLDC) motor is a rotating electric machine, where the stator is a classic 3-phase stator like that of an induction motor, and the rotor has surface-mounted permanent magnets; see Figure 2-1.
Are brushless motors AC or DC?
A brushless motor is sort of an AC motor, using a brushless motor controller which takes DC input and chops that DC into a rotating three-phase AC signal to drive the motor with.
Can I use a 7.4 v battery instead of 7.2 v?
Of course, you can use a 7.4 volts battery instead of 7.2 volts on your RC car. However, it must be within the range of voltages the electronic speed control (ESC) of your car can handle. If 7.4 volts is not in the range of voltages and you use it, you could damage the motor and ESC beyond repair.
