FAQ

1.How could you help me select an appropriate motor solution for my application?

A:The absolute minimum information required to properly select a motor solution is the supply voltage, available continuous and peak current, load torque, speed at load, and desired motor technology (brush or brushless).  To be sure, the more application information you can provide, the more accurate and exact motor we can offer or quote to you.    

 

2.How do I calculate the rated speed or the speed at a specific torque for a motor or gearmotor?

A:

The output speed for a motor or gearmotor is given by the equation below:
               w = [VS - (I x Rmt)] / (KE x N)

Where

w = Speed
VS = Supply Voltage
I = Current (Obtained from previous equation)

Rmt = Motor Terminal Resistance
KE = Back-EMF Constant
N = Gear Ratio (Equals 1 if there is no gearbox)

3.What environmental considerations are there?

A:

Typical environmental temps for the motor should be in a low humidity environment with an ambient temperature range of –20 C to +50 C.  BLDC motors do have IP ratings associated to them and limited customization can be done to increase the IP rating.  If severe conditions require IP ratings of IP54 or higher, a customized motor construction is required to accommodate this need.

 4.Should I use brushless motor or brush motor in my application?

A:

It should be important to decide when it comes to determining which motor you will need for whatever application or project you are realizing, and your choice will depend on a variety of factors.  Some major issues you will need to consider are target cost, amount of power you will need and how long you need it to last.  

If you have a project or application where you will only need a motor for short term use or light daily duty, you may prefer a cheaper one that may wear out more quickly.  If your job requires a motor that will last as long as possible, you will probably want to consider a BLDC motor, for reasons which will become apparent.

5.What is a brushless motor?

A:

A Brushless DC (BLDC) motor is a rotating electric machine where the stator is a classic three-phase stator like that of an induction motor and the rotor has surface-mounted permanent magnets.  

BLDC motors often incorporate either internal or external position sensors to sense the actual rotor position or the position can be detected without sensors.  The BLDC motor is driven by rectangular voltage strokes coupled with the given rotor position. The generated stator flux interacts with the rotor flux, which is generated by a rotor magnet, defines the torque and thus speeds of the motor. The voltage strokes must be properly applied to the two phases of the three-phase winding system so that the angle between the stator flux and the rotor flux is kept close to 90° to get the maximum generated torque. Due to this fact, the motor requires electronic control for proper operation.

6.What is a brush dc motor?

A:

Brush DC Motor provides precision control of speed, driven by a direct current. Noted for a particularly high ratio of torque to inertia, the Brush DC Motor has the potential to supply three to four times more torque than its rated torque.  The Brush DC Motor consists of six different major components: the shaft, armature/rotor, commutator, stator, magnets, and brushes. The Brush DC Motor offers stable and continuous current, using rings to power a magnetic drive that operates the motor's armature. 

7.What is the lifetime of brush motor?

A:

This is a tricky question to answer in a short paragraph.  The life of the brushes, bearings, and gearbox (if used) all play an important role in the longevity of a Brush DC Motor. Most commonly, Brush DC Motor life expectancies range from 1,000 to 5,000 hours of operation, although actual service life varies.

Brush DC Motor design, operating current, speed, voltage, rotation direction, duty cycle and other conditions are all contributing factors. 

Special shaft and other mechanical characteristic optional.
