Paired engines Frederick series FK They are a one-sided elongated shaft, which is connected by an end cap to a central hole. Such a compact installation is compensated by the interaction of four vibration motors and provides linear vibration at high operating moments, while having low energy consumption. A coupling is used to connect the motors. The motors are connected using a flexible cable for high mechanical loads, for example, H07RN-F or A07RN-F according to DIN VDE 0282.
The engines have roller bearings with high load capacity and long service life, lubricated with a special lubricant. The designation of the standard size is presented as follows: The number of the first block=operating torque in kg * cm (operating torque=2 x static torque), followed by a hyphen, and then the pole number, where: 4=1460 rpm, 6=980 rpm (main frequency 50 Hz), followed by the second line the size is specified.
