Coupling fixing |
(1) There are five ways to fix coupling onto shaft as below. |
Coupling installation |
♦ To maintain installation completeness of all kinds of couplings, it's recommended to install as follow charts to avoid direct contact of two shafts and to have a regular run. |
Motor reference |
♦ Induction motor (1) More than triple torque occurs in case of running momently. (2) Shaft axis center of the motor has ±1.5mm movement back and forth while running, and it's not recommended to use spiral beam type. (3) DC motor could be used in working environment with dust.
♦ Stepping motor (1) Without triple torque in case of running momently, but max. rated torque of motor occurs. (2) Larger torque in low speed than servo motor in same level. (3) Higher RPM, smaller torque in motor. (4) Motor have temperature rise in case of running continuously.( to improve by using disk type coupling) * Force output in stepping motor is smaller than servo motor.
♦ Servo motor (1) More than triple torque occurs in case of running momently. (2) Under rated RPM range, cause rated torque. (3) Same torque produce in low speed and high speed. (4) Temperature rise is small in case of running continuously.
♦ Encoder (1) Built-in servo motor, has tiny driven torque. (2) Or connected to stepping motor. (optional) |
