Product Description

MSK075E-0450-FN-M2-UG0-RNNN is a liquid-cooled servo motor. Liquid cooling dissipates the heat generated by the motor by circulating a liquid coolant through the motor's housing. The liquid coolant absorbs the heat from the motor and carries it away, where it can be dissipated by a cooling system. This can be achieved by the use of a liquid-cooled jacket around the stator or by running cooling liquid through internal channels within the stator. Liquid cooling method is more effective than air cooling, as liquids have a higher thermal conductivity and specific heat capacity than air. This means that a given volume of liquid can absorb and carry away more heat than an equivalent volume of air. Liquid cooling also allows for more precise temperature control, which can be important for maintaining the optimal operating conditions of the motor and prolonging its lifespan.

Additionally, it can also make the motor more compact by allowing for a smaller cooling system. However, liquid cooling requires a closed-loop system, which includes a pump, radiator and other components, that can add complexity and cost to the system. It also requires maintenance and service to make sure the system is working properly. Continuous torque rating of the MSK075E-0450-FN-M2-UG0-RNNN motor at standstill with liquid cooling is 39.9 Nm. The continuous current at standstill with liquid cooling is 35.3 Amps. Thermal time constant of the motor is 10 minutes and its speed rating is 6000 RPM. The motor dissipates 1 kilowatt of power as heat. The inlet temperature for the coolant must be between 10 and 40 degrees Celsius. the required coolant flow rate is 1.5 liters per minute. The coolant duct is made of die-cast aluminum. The motor has a plain shaft, 240-degree rotatable power connector and a multiturn optical encoder with EnDat 2.1 interface.
