I never considered weight. I see what you mean. I'm looking at some other smaller motors like the mars ME series and they're about 35 lbs (compared to 51-62 lbs for the D&D). The Mars are also smaller.
Here's another example of the prices versus specs I need help with:
ME0913 - $820
3-Phase Permanent Magnet Brushless Motor
24 - 96 Volts
Efficiency of 92%
12 KW (180 amps DC) continuous @ 96 Volts
23 KW for 1 minute (600 amps DC) Peak @ 96 Volts
Peak Stall Torque of 90 Nm (66 ft)
Designed for long life. No brush maintenance.
8" OD, 7.17" long (w/o shaft)
7/8"x 1-5/8", 3/16" key shaft
35 Lbs
ME0201014201 - $425
3-Phase Permanent Magnet Brushless Motor
24 - 72 Volts
Efficiency of 90%
90 amps continuous current at 48 VDC
Designed for long life. No brush maintenance.
8" OD, 7.17" long (w/o shaft)
7.9" OD, 5.8" long (w/o shaft)
22 Lbs
Can someone explain the differences in the two? There are some specs on the first motor that aren't listed on the second motor, such as "23 KW for 1 minute (600 amps DC) Peak @ 96 Volts"
