12VDC Gear Motor: 21 N-m (15.5 ft-lb) torque at 6 RPM.

## What is the torque of DC motor?

Torque equation of a DC motor

When armature conductors of a DC motor carry current in the presence of stator field flux, a mechanical torque is developed between the armature and the stator. Torque is **given by the product of the force and the radius at which** this force acts.

## What is the speed of 12V DC motor?

DC Motor High Torque Permanent Magnet DC 12V High Speed **12000 RPM** Brush Small DC Motor.

## Do DC motors have torque?

The D.C. motor, by its very nature, **has a high torque vs.** **speed characteristic**, enabling it to deal with high resistive torques and absorb sudden rises in load effortlessly; the motor speed adapts to the load.

## How much weight can a 12V DC motor lift?

Weight: **100 gm(Approx.)** RPM: 100 Operating Voltage: 12V DC Gearbox: Attached Plastic (spur)Gearbox Shaft diameter: 6mm Shaft Length: 21 mm Torque: 1.2 Kg-cm. No-load current = 60 mA(Max) Load current = 300 mA(Max).

## Which is proportional to the torque in dc motor?

For DC Machine, torque is directly proportional to **armature current and flux**. In dc shunt motors, flux is constant (not dependent on armature current). Hence torque is proportional to armature current.

## Is torque proportional to power?

The relation between torque and power is **directly proportional to each other**. The power of a rotating object can be mathematically written as the scalar product of torque and angular velocity.

## Which DC motor is best?

**Series wound DC motors** are best for applications that require high startup torque, without the need for speed regulation. Like a shunt motor, as a load is applied to a DC series motor, the motor speed decreases, which reduces the back EMF and increases the net voltage.

## Which is the fastest DC motor?

The British appliance manufacturer Dyson claims to have developed the world’s fastest, most efficient motor for domestic appliances. **The Dyson Digital Motor (DDM) v2** is a single-phase brushless DC motor, which operates at speeds up to 104,000 rpm with a claimed efficiency of 84%.

## How is torque measured in DC motor?

Keep it simple. To measure the torque simply **create a transversal arm attached to the motor using a known length**. Let the whole motor free to turn (not the shaft, the outside case) along with the attached arm. The arm tip, opposed to where it’s attached to the motor, can then be placed on a balance.

## What is field current in DC motor?

: **the current supplied to the field windings of a generator or motor to establish the magnetic field for its operation**.
