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.
