What are the types of cooling used in induction motor?
In general, water-cooled motors can be divided by two types of cooling – jacket cooling and cooling by heat exchanger (air/water). When using a heat exchanger the airflow is either arranged by a fan on the motor shaft or by an independent motor.
What is ic01 cooling system?
The IC 01 cooling class is a cooler where the air directly flows through the interior of the machine as a coolant. The heat generated in the motor (stator and rotor) is blown through the motor by a fan that is mounted on the rotor.
What is IC411 cooling?
IC411 – TEFC – Totally Enclosed Fan Cooled. (own fan ventilated) IC416 – TEFV – Totally Enclosed Force Ventilated. (ventilated with independent fan) IC418 – TEAO – Totally Enclosed Air Over.
How are induction motors cooled?
For AC induction motors, cooling air is usually circulated internally and externally by one or more fans mounted on the rotor shaft. To allow for operation of the machine in either direction of rotation, fans are usually of the bi-directional type and made of a strong plastic material, aluminum, or steel.
What is IC611 cooling?
IC611 – (formerly IC 0161) – CACA – Air-Air cooling with integral fan on motor’s shaft inside stator and heat exchanger with open external circuit with fan on motor’s shaft.
How are electric motors cooled?
Air-cooled motors have a fan that blows air onto the motor housing, thereby cooling it. Motors with fluid cooling are cooled with water or oil that flows through cooling channels in the motor.
Do electric motors need a cooling system?
All rotating electrical machines generate heat as a result of the electrical and mechanical losses inside the machine. Losses are high during starting or dynamic braking. Also, losses usually increase with increased loading. Cooling is necessary to continuously transfer the heat to a cooling medium, such as the air.
Why do DC motors get hot?
Electrical overload caused by excessive voltage supply or overwork by drawing more current will lead to overheating issues. As the motor works harder or under unusual load, heat will be the chief byproduct, leading to failure.
How do you reduce electric motor heat?
Operating electric motors in poor environmental conditions also leads to excessive heat. Associated problems include clogged ducts and high ambient temperature. One way to keep your motors cool is by reducing the excessive load that the motor handles.
How are EV motors cooled?
In an electric vehicle, the cooling system is regulating the temperature of the battery pack and some of the electronics. Most electric vehicles use a cooling loop. This loop usually contains an ethylene glycol coolant. The coolant is circulated through the batteries and some of the electronics, using an electric pump.
What is the cooling principle of IC 511 Motors?
The pipe or tube cooling principle for IC 511 motors ensures particularly efficient, uniform cooling, because the cooling pipes are wound symmetrically around the laminated core. The primary and secondary coolants are moved by fans on the motor shaft.
Why choose IC 511 three-phase squirrel cage motors?
The generously-sized roller bearings of IC 511 three-phase squirrel cage motors enable high load motor capacities, and ensure a long lifespan. Because IC 511 squirrel cage motors are no longer standard in Europe today, it can be hard for operators to find a replacement for old machines of this construction type.
What is the best cooling method for motors?
Air-air cooling is a common cooling method for motors. There are usually three ways of IC611.IC616 IC666. Because the rotation of the rotor drives the air to blow all parts of the motor, the natural cooling is enough for the motor with small capacity. However, in most motors, internal or external ventilation must be used to enhance cooling.
