Hi Stu,

Here is the information on the 30S-1 Blower Replacement Motor:

Dayton Electric Model # 4M093

Type: Shaded Pole
RPM: 3000
H.P. 1/40
Rotation: CCW
Bearing: Sleeve
Therm. Protection: Auto
Shaft: 1/4 X 2 1/4

I purchased mine from:=20

Winan's Inc.
G 1460 E. Hemphill Road
Burton, MI 48529-1202

Phone: (810) 744-1240
FAX: (810) 744-1424

The only problem I have found was that the motor was designed to have =
air pulled across it for cooling. As this doesn't happen in the 30S-1, =
mine was shutting down after about 2 hours of operation. To correct this =
problem, I connected a 50 ohm, 25 watt power resistor in series with the =
motor. This reduced the RPM only slightly, and made the motor run much =
cooler. I have not had it shut down at all, and at times the amp is on =
for 8-10 hours.

  Fred,

  Can you please pass along the blower info, such as part number, speed,
  rotation direction, and whether it is an oil or non-oil type.

  Thanks for passing this along.
  Stu, k2qde

  The motor that I ordered from Winan's Inc. arrived today. It cost =
about the
  same as buying it from Grainger without all the hassle. I'll list the
  address and phone number again in case anyone else needs the motor.
