Product Description

The Kollmorgen STF3640-4977-61-56BC is a 1/5 HP, 90V DC Motor from STF Series. This model is specifically designed for applications where frequent washing of equipment is desired and often referred to as a Washdown Duty motor. The STF3640-4977-61-56BC comes with a removable base and features Class H insulation. It is an uncooled motor and has no shaft-mount fan.

The insulation material utilized in this model makes it capable to withstand high operating temperatures. Motors with Class H insulation can be operated with winding temperatures up to 180 degC. The STF3640-4977-61-56BC comes housed in a specially designed TENV enclosure. A non-ventilated and sealed enclosure prevents the motor from moisture ingression. This model and its other counterparts are widely considered in the food processing and bakery industries. As far as its design features are concerned the STF3640-4977-61-56BC is an IP65 rated motor that is built according to the requirements as provided by NEMA MG1-1.26.5. While operating at its full speed, this motor draws 5.1 amperes of current at 90VDC and produces 18.0 lb,-in torque. The current required for shaft breakaway or the peak current value for this motor is 67A and it has a resistance 0.95 ohm.

The inertia and inductance values for this motor are 6.3 lb,-in and 4.38 mH respectively. This motor can rotate at a speed of 1750 revolutions per minute (RPM) provided that the applied DC voltage is within the required limits. This motor weighs around 26 lb. It is an SCR-rated motor that can be controlled through a Silicon Controlled Rectifier.
