Since the torque constant depends on the magnetic circuit, the objective during motor design is to have the maximum flux generated by the magnet going through the winding. One way to increase the torque constant, is to use stronger magnets, such as NeoFe which today are close of 50 MGoe.

## How do you give a motor more torque?

The way to increase the torque that the motor delivers, mechanically, would be:

- To increase the diameter of the wire in the windings (which is to say, completely remanufacture the motor)
- to have the output shaft coupled to a gear reduction setup, which would lower the final drive rpms, but increase the torque.

## Does increasing voltage increase torque on motor?

Increasing the voltage above normal parameters will effectively increase the torque because of a stronger voltage source being able to provide more current with the same resistance, but the increased voltage is more likely to increase speed—at least until the motor overloads and . . .

## What determines the torque of a brushless motor?

Since torque is a function of current in a brushless motor, and current is equal to the voltage drop in the circuit divided by the circuit resistance, when the back EMF is equal to the forward applied voltage minus the circuit losses the functional torque of the motor will reach a point where it runs out of the torque …

## Does increasing voltage increase torque?

In the situation where the motor is not yet turning, doubling the voltage will indeed double the current and double the torque — because the voltage is acting against the resistance of the wire in the windings only.

## How do you increase torque?

An effective modification that will increase torque significantly is to install a turbo or supercharger. Forced induction forces air into your engine, increasing the power the engine provides. Depending on the torque curve you prefer, a turbocharger will need time to spool before it provides torque benefits.

## Does torque increase with current?

As the torque is proportional to the product of D and Q components, it is obvious that larger current produces larger torque.

## Does voltage or current affect torque?

The voltage is the only matter variable when running a motor. More voltage=More electromagnetic=more power=more torque. More current is not equal to more torque.

## Does higher voltage mean faster motor?

Yes the speed of the DC motor is increased by increasing the armature voltage. Therefore, the speed of the motor is proportional to the applied DC voltage if the field flux is constant.

## How much torque does a brushless motor have?

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).

## Do brushless motors have constant torque?

The motor torque constant for brushed DC motors and brushless motors tells you how current relates to torque. In this equation, T is torque, Kt is the torque constant, and I is current. Kt has units of Newton-meters per Amp.

## Does lower Kv mean more torque?

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. A high Kv motor has fewer winds of thicker wire that carry more amps at fewer volts and spin a smaller prop at high revolutions.

## What happens to speed when you increase torque?

For a constant power speed decreases when torque increases. If you want to maintain the same speed (rpm) even on a up-hill, you need expend more power/fuel, in this case torque increases to maintain the same speed.

## What is the relation between torque and voltage?

The torque of the motor is directly proportional to the square of the supply voltage. With the decrease in voltage, the torque will decrease and the RPM of the motor will also get decreased. The torque of the motor is directly proportional to the square of the supply voltage.
