Product Features:
Top runner motors are heat resistant class F for improved thermal resistance and increased reliability.
The streamlined design of the electrical part and the high cooling effect of the aluminum alloy frame reduces the temperature of the stator coil by about 10 to 20 degrees Celsius. Coil insulation life is about 2 times longer than standard motors. The bearing life is about 2.5 times longer.
* Please note that the life of the product is estimate, and it will vary depending on the usage environment and operating conditions.
Low loss design for high efficiency, so the motor generated heat is lower than a standard motor. Therefore, there is a temperature margin even at low speeds at inverter drive (constant torque characteristic). (when using our sensorless vector control inverter)
The mounting dimensions of the top runner motor (frame number, shaft diameter, foot hole position, etc.) are identical to the standard motor (18.5 - 55 kW equivalent, the total length dimensions may vary in addition to the width and height).
