Spaceman Motor Amp Draws

Motor Amp Draws

Documentation :: Motor Amp Draws


Introduction

When diagnosing potential machine issues, it can be helpful to disconnect the belts from the motor and confirm the motor amp draws.  The below chart indicates the ideal amp-draw that should be measured on the motor for each model when the motor is under no load.   You should be able to measure the same no-load amp draw with the belt disconnected, as well as when the motor is running with nothing in the cylinder and the motor only driving the gear reducer.  

If you experience a high-amp draw with the belt off, the motor is likely bad and needs replacing.  Please see the Soft Serve: Troubleshooting 3 Phase Motor, Spaceman SS: Troubleshooting 1-Phase Motor, or FB: Troubleshooting 1-Phase Motor article for more information.  If you experience nominal amp draw with the belt off, and high amp draw with no load on the gear box, the belt is too tight or the gearbox is bad and needs to be replaced.

Info
6210-C models do not have inverters; note that motor amp draws will decrease with the compressor on.
Notes
When setting viscosity, it must be set higher than the no-load amp draw range when the compressor is on (usually above 4.25A)
