Product Description:

The Kollmorgen makes the MT704B2-91A1-001 a high-performance motor made for precise tasks in industrial automation. The strong design and high-tech features of this MT7 motor make it reliable and efficient in tough conditions. Modern technology is built into the motor that makes it suitable for many uses that need precise control and high torque.

The MT704B2-91A1-001 motor operates at a rated voltage of 230 V RMS (line-to-line) and has a peak current of 104 Amps RMS and a stall current of 29.9 Amps RMS. The motor generates a consistent torque of 31.9 Nm when the temperature is adjusted to 40°C, and it can achieve a peak torque of 90.4 Nm at that temperature. The motor's maximum speed is 3000 RPM that provides it with a significant degree of adaptability for a wide variety of tasks. The MT7 is equipped with a 512 SINCOS encoder, which provides precise input for improved control. The power is utilized efficiently, as the line-to-line impedance is also 0.170 Ohms at 25°C. The motor is suitable for applications that necessitate both dependability and high speed, as evidenced by these specifications.

The motor has a gear reducer that can handle a top speed of 3500 RPM. When it comes to size, the MT704B2-91A1-001 motor is about 27" x 8" x 8 that makes it small but strong for many uses. The motor also has an insulation class rating of F, that makes sure it works well in certain situations. A strong build is also helped by the fact that the motor weighs about 15 kg. We provide a one-year replacement warranty and accelerate the delivery of the product worldwide to satisfy our customers' requirements.
