What the difference in RC motor turns mean?

Generally speaking the more Kv a motor has, the more RPM and more power. The number of turns indicates how much wire is wrapped inside the motor. A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor.

How does the number of windings affect a motor?

The number of windings determines the strength of the magnetic field. The more windings, the stronger the field. The number of poles determines the speed of the motor. The number of windings on the poles, the voltage, and the number of phases, determines the strength (HP & torque) of the motor.

What makes a motor more powerful?

Strength of a motor: The strength of the motor (torque) is determined by voltage and the length of the wire in an electromagnet in the stator, the longer the wire (which means more coils in the stator) the stronger the magnetic field. This means more power to turn the rotor.

How does the efficiency of a motor change with load?

Most electric motors are designed to run at 50\% to 100\% of rated load. Maximum efficiency is usually near 75\% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50\% load.

How many turns is a Velineon 3500?

The Velineon 3500 motor is a 10-turn, 3500 kV motor optimized for the best speed and efficiency in lightweight 1/10 scale models.

Does more turns mean more torque?

The higher the number of turns greater is the torque generated and hence greater is the power delivered. However that also means less RPM rating for your rc car electric motor. Generally less turns are preferred for making the rc car run faster.

Why bigger motors are generally more efficient than smaller motors?

To maintain same flux density as in a larger motor, larger number of turns is needed. Current is lesser in a smaller motor, so conductor area is smaller but can have the same current density in an ideal motor. Thus, the resistance is larger, but I2r loss will be almost same percentage as in an ideal larger motor.

What determines the horsepower of an electric motor?

Electric motor horsepower To determine the horsepower of an electric motor, you need to know the voltage input, current draw in amps, and the rated efficiency of the motor. Thus, the horsepower of this motor is 480 volts × 50 amps × a 92\% rated efficiency ÷ 746, which = 29.59 hp.

Why does the efficiency of motor reduce when it operates at lower loading?

Originally Answered: why is efficiency of a motor reduced extraordinarily when the motor works underloaded (lesser than half of full load)? This is due to motors drawing reactive power / current which causes winding losses. When running at full power these are much lower.

Are smaller motors more efficient?

Motor efficiency can be derived from two factors: the size of the motor and its efficiency quality. For smaller motors in particular, size is an important factor that affects efficiency. For larger motors, it is the efficiency classes that matter more.

How fast is a Velineon motor?

Already capable of 35+mph, these models will still benefit dramatically from the addition of a brushless system. The Velineon system consists of a new brushless motor and the powerful VXL-3s Electronic Speed Control.

What does the number of turns in an electric motor mean?

The number of turns indicates how much wire is wrapped inside the motor. A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor.

What is the effect of turn rating on motor speed?

A higher turn number means more wire and thus more resistance, resulting in a slower motor. So turns with a lower number means a faster motor. The turn rating is inversely proportional to the power generated by the motor.

What is the difference between kV and turns in a motor?

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. If Kv is like horsepower, then Turns is the physical attribute of a motor. The number of turns indicates how much wire is wrapped inside the motor.

What happens to a motor when the power is turned off?

There are also losses in the stator core of the motor which are caused every time the magnetic field changes directions. Ideally, the core would not retain any magnetism when power is shut off, but in actual practice, a very small residual magnetic field is left in the stator when the power is turned off.
