Product Description

The Kollmorgen MTC304B1-R1C1 is a brushless motor which belongs to the Goldline XT series. This series of motors provides a range of standard options such as IP65 / IP 67 sealing, four stack lengths, integral failsafe electromagnetic brake, NEMA 34 / 100 mounting and resolver or encoder feedback. The Goldline series of motors is approved by CE and UL. This motor series is compatible with Servostar CD digital servo amplifiers. The MTC304B1-R1C1 motor has a 90-millimeter frame length and the length of the magnet stack is 4. Output power specifications for the motor are 1.85 Horsepower and 1.38 kilowatts. The speed of the MTC304B1-R1C1 motor is 6000 RPM. The motor continuous torque (stall) at 40 degrees Celsius and 25 degrees Celsius is 2.58 Nm and 2.73 Nm respectively.

The peak motor torque is 7.41 Nm. The steady-state line current of the MTC304B1-R1C1 is 5.53 Amps which can go up to a peak value of 20.9 Amps. The torque sensitivity (stall) is 0.473 Nm/Amp. The line-to-line back EMF is 28.6 VRMS/kRPM. DC resistance of the MTC304B1-R1C1 at 25 degrees Celsius is 1.70 Ohms. The rotor inertia is 0.000808 kg m². The static friction is 0.035 Nm. Weight of the MTC304B1-R1C1 with and without brake is 4.3 kilograms and 3.3 kilograms. The motor comes with several features including holding brake rated for 24 Volts DC, resolver for feedback, NEMA 100 mounting option, 90-degree swivel receptacles for power / feedback connection and a seal on the motor shaft. Function of the shaft seal is to prevent oil leakage and ingress of dust and moisture which are harmful for the motor bearing. The seal should be inspected periodically and replaced if required.
