Is this motor usable?

I am unclear on whether they are reliance or electrocraft...here's
the specs on them:

Motor number E-690
Continuous Stall Torque (Oz-In) 352
Peak Torque (Oz-In) 1760
Nominal Terminal Voltage (V) 120
Nominal Operating Speed (RPM) 1750

Rotor Inertia (Oz-In-s2) 0.068
Damping Constant (Oz-In/kRPM) 1.8
Thermal Resistance (C/Watt) 1.6
Maximum Armature Temperature (C) 155
Maximum Friction Torque (Oz-In) 8.0
Terminal Resistance, Nominal (Ohms) 4.3
Weight (lbs) 8.0

Torque Constant, kt (lb-In/Amp) 5.5
Back EMF Constant, ke (V/kRPM) 62
Maximum Continuous Current (A) 4.0
Maximum Peak Current (A) 20.0

I plan to use them on a BP size mill. They also come with a 500
line hp encoder too.
