The specification of SLT42BLF20 24V 36V 48V DC Electric Brushless DC Motor
|Number of poles||Â||8|
|No load speed||RPM||5300||5400||5200||5200|
1,What custom modifications are available?
Â 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 aÂ brushless motor versus aÂ brush style motor?Â
No brush noise, efficient, durable, robust, easy to cool
Synchronous speed control
Position and Speed Servo (open/closed loop)
3,How can IÂ 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 =Â 48 inoz =Â 3 inlb|
|Assumed Eff %:||80 %|
|Power Output:||( Speed xÂ Torque(inlb) )Â / 84.5||=>||(3600 xÂ 3 )Â / 84.5||=||127 Watts Output|
|Power Input:||Watts Output /Â Assumed Eff%||=>||127 /Â 0.8||=||159 Watts Input (Required)|
|Current Requirement:||Watts Input /Â Voltage||=>||159 /Â 12||=||13.2 Amps (Minimum)|
4,What environmental considerations are there?
Typical environmental temps for the motor should be run in aÂ low humidity environment with an ambient
temperatureÂ range of -20 CÂ to +50 C. brushless motors do have IP ratings associated to them and limited
customization can beÂ done to increase the IP rating. If severe conditions require IP ratings of IP54 or higher,
a customized motor constructionÂ is required to accommodate this need.
5,Are there any noise benefits of aÂ Brushless motor?
Yes, with the elimination of brushes, brushless motors can be regulated to slower operating speeds without
sacrificing torque.Â Brushless motors can also utilize skewed magnets to reduce the effect of cogging.
