Product Details

  • Melservo HC Servo Motor with Key (HCSFS352K)
  • Manufacturer: Mitsubishi
  • Series: MELSERVO HC

Product Description

The Mitsubishi HC-SFS352K (HCSFS352K) is a Melservo HC servo motor with a key. The servo motor has a moment of inertia is 82.0 J(x10^-4kg x m^2) or 448 J(oz x in^2) since it is a normal motor without a brake. The servo motors speed is usually 2000rpm, but a faster speed is permitted at 2500rpm. The fastest speed which is sanctioned (although only for a short time) is 2875rpm. The HC-SFS352K servo motor with key has a torque which is rated to be 16.7 (N x m) or 2364.7 (oz x in). However, the torque is allowed to be performing at 50.1 (N x m) or 7094.2 (oz x in). Then the current is computed to be 17.0A, but it can be permitted to function is 51.0A.

These four amplifiers, the MR-J2S-350CP, MR-J2S-350B, MR-J2S-350A, and MR-J2S-350CL, may attach to this servo motor, the HC-SFS352K. This is how the servo motor with a key may attach to the amplifier that is selected. The first means is to attach an encoder cable to the encoder of this servo motor, and then the cable needs to link with the CN2 port. For a power supply connection, the HC-SFS352K servo motor must connect to the three top screw terminals: U, V, and W. This connection is accomplished by a power supply cable which serves as linking intermediary.

The HC-SFS352K servo motor is of the medium capacity, this is because it has a speed evaluated to be 2000rpm. It is also a medium inertia motor since it is from the HC-SFS series.
