How do you calculate the loading capacity of a DC motor?

The formula that relates mass, force and acceleration is: F = m*a , where F is the force, m is the mass and a is the acceleration. So a = F/m would be 14.715 kg*m/s² divided by 2 kg and therefore: ~7.358 m/s².

How do you calculate motor load capacity?

Por = Nameplate rated horsepower Load = Output power as a % of rated power Pi = Three-phase power in kW η = 0.7457 x hp x Load Pi Page 8 8 By definition, a motor of a given rated horsepower is expected to deliver that quantity of power in a mechanical form at the motor shaft.

How do you find the maximum load of a DC motor?

Your desire to obtain the maximum load will be defined by your requirements and a specific speed. P(mech) = (Torque{rated} x speed {RPM}) / 9550. So if you are running at anything other than rated speed and you still require the same torque the power consumed less the losses will give you P(mech) or output power.

How do I calculate RPM?

RPM = a/360 * fz * 60

RPM = Revolutions per minute. Example 1: Drive step resolution is set for 1000 steps per revolution. Example 2: Drive step resolution is set for 500 steps per revolution. With input frequency of 1000hz, .

What is load of a motor?

The load can basically be anything. For example, it can be a resistor, or a capacitor or an inductor, or a transistor, or a motor, or an air conditioner etc. The term “load” can also mean “the amount of power” or “the amount of current” drawn by the thing that is connected to the output of the circuit.

What is the capacity of DC motor?

Typical DC motors may operate on as few as 1.5 Volts or up to 100 Volts or more. Roboticists often use motors that operate on 6, 12, or 24 volts because most robots are battery powered, and batteries are typically available with these values.

How much weight can a 12V DC motor pull?

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).

What is 120 in motor speed formula?

The equation for calculating synchronous speed is: S = 120 f/P speed = constant (120) times frequency of power source (60 Hz) divided by number of poles used in the motor (P).

What is 1 rpm?

Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min, or with the notation min−1) is the number of turns in one minute. It is a unit of rotational speed or the frequency of rotation around a fixed axis.

How fast is 6000 rpm in mph?

So for every 1000 rpm increases speed by 13.33 mph. (40 divided by 3) This will not work with automatic transmissions, because numerically the gears are changing. AN EASY DOWN AND DIRTY METHOD, if you are in third gear at 3000 rpm and traveling 40 mph, in theory at 6000 rpm you should be traveling 80 mph.

How fast is 7000 rpm in mph?

7000 rpm would be about 91.7 mph.

What is the formula of load?

Multiply the mass of the object by the gravitational acceleration of the earth (9.8 m/sec2), and the height in meters. This equation is the object at rest’s potential energy. Potential energy is measured in joules; this is the load force.

What is voltage load?

“Load Voltage” is the voltage that a power source is able to supply when it is “loaded” at its rated “load value.” It is dependant upon the internal resistance or impedance of the source. Let’s take a car battery as an example. … Therefore, the “load voltage,” aka “voltage under load”, is 12 volts.

What are the types of load torque?

Types and Characteristics of Load Torque

  • Classification of load torques :
  • Active Load Torques:
  • Load torques which have the potential to drive the motor under equilibrium conditions are called active load torques.
  • Passive Torque:
  • Load torques which always oppose the motion and change their sign on the reversal of motion are called passive load torques.
