FAQ
1,What custom modifications are available?
SLT can provide motor with customized shafts, mounted encoders, various controls
(integral, hall only, or sensorless), and alternate magnet materials for power density.
2,What are the advantages of using a brushless motor versus a brush style motor?
No brush noise, efficient, durable, robust, easy to cool
Linear current/torque
Synchronous speed control
Position and Speed Servo (open/closed loop)
Customizable Performance
Extended Life
3,How can I calculate my power needs?
A simple formula can be used to roughly determine what is needed power-wise.
Here's an example:
| Motor Speed: | 3600 RPM |
| Motor Torque: | 340 mNm = 48 inoz = 3 inlb |
| Voltage: | 12VDC |
| Assumed Eff %: | 80 % |
| Power Output: | ( Speed x Torque(inlb) ) / 84.5 | => | (3600 x 3 ) / 84.5 | = | 127 Watts Output |
| Power Input: | Watts Output / Assumed Eff% | => | 127 / 0.8 | = | 159 Watts Input (Required) |
| Current Requirement: | Watts Input / Voltage | => | 159 / 12 | = | 13.2 Amps (Minimum) |
4,What environmental considerations are there?
Typical environmental temps for the motor should be run in a low humidity environment with an ambient temperature
range of -20 C to +50 C. brushless 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.
5,Are there any noise benefits of a Brushless motor?
Yes, with the elimination of brushes, brushless motors can be regulated to slower operating speeds without sacrificing torque.
Brushless motors can also utilize skewed magnets to reduce the effect of cogging.
