Humidicore™ Motor Options

Motor Options

The Humidicore™ depends upon a reliable motor to turn the core. Core rotation speed controls the outlet dew point. A variable speed motor is usually desired, although some fuel cell plants work fine at a fixed speed.

Brushless DC motors work best because of their long lives and non-sparking characteristics.

Emprise offers three motor models:

Manufacturer	Speed (rpm)	Torque (in-lbf)	Voltage (dc volts)	Maximum Power (watts)
Merkle-Korff (M-K)	0-55	15	12 to 36	24
Brushless Motor Corp (BMC)	0-40	30	12, 24, 48	50
Brushless Motor Corp (BMC)	40	30	12,24,48	50
Brushless Motor Corp (BMC)	0-60	60	12,24, 48	111

The chart below illustrates the outline dimensions of these motors. The torque requirements of the various cartridge sizes are as follows:

Nominal Core Diameter	Torque (in-lbf)	Power Consumption (watts)
4	10	16
6	15	25
8	20	35

Any motor that meets these requirements may be used.
