- High performance rare earth permanent-magnet rotors, high torque with low inertia, good dynamic response.
- 3 phase sinewave design provides smooth operation in low speed.
- No noise, maintenance free, long service life.
General technical characteristics
Applicable environmental characteristics: The motor can meet the rated output power under normal pressure at an altitude of 5 to + 40 ° C and the altitude does not exceed 1000 meters.
Power loss: at 40 ~ + 50 ℃, the altitude exceeds 1000 meters, the power decreases by 1.5% for every 100 meters increase.
Power-loss brake (optional): When the motor is de-energized or suddenly powered off, the brake works to keep the motor shaft from rotating to avoid personal injury or equipment damage.
Bearing characteristics: All DC brushless motors use imported single-row double-sided dust-proof ball bearings, high and low temperature grease, and their life is not less than 20000 hours under normal load conditions.
Electrical technical characteristics
Electrical technical characteristics include the servo unit to avoid interference from peripheral electromagnetic equipment and interference with other equipment, which requires good shielding measures. The ground wire of the motor must be thick and short.
(Standard ground), at the same time, the shielded wire must be connected to a sufficiently large metal plane to prevent high-frequency interference. Strictly distinguish the shielded wire and the ground wire, and do not confuse them. Motor and drive
The connection between the actuators must be shielded, its reactance capacity, the motor power cable must be at least 150pF / m, and the position feedback cable must be at least 120pF / m.
Mechanical technical characteristics
Motor housing parts must not have heavy pressure and external impact force, so as not to damage the motor. It is forbidden to clean the surface of the mechanism during the operation of the mechanism to avoid causing injury. Servo motor
During the installation process, the concentricity between the load shaft system and the motor shaft must be ensured to avoid motor shaft breakage and damage to the load mechanism. If the shaft end of the motor is equipped with timing pulleys and gears,
Helical gears and planetary gears must be checked with reference to the technical parameters of the motor's axial (Fa) and radial (Fr) loads to avoid damage to the motor; the calibration standards are as follows:
The diameter of the step pulley, gear, helical gear and planetary gear dmin≥2Tm. Tm is the peak torque of the servo motor.
