For horizontal motion of the seat rail, it relies on the lead screw connected to a DC motor. For vertical motion, the same mechanism is placed in the center of the structure so that the weight of human body is evenly distributed throughout the whole structure when lifting and lowering the car almotor DC stepper motor (ARM24SMK-H100) is icatio:Frame size: 30 mmType: Harmonic Geared TypeShaft type: Single ShaftElectromagnetic brake: WithCable WithoutDriver type Built-in Controller TypeMaximum holding torque 2.4 N· inertia J 19×10^-7 kg·m^2Speed range 0 to 35 minGear ratio: 100Resolution setting: 1000 p/r: 0.0036 º/PulseRated torque: 2.4 N· motion (load torque): 1.5 arcmin or less(±0.12 N·m)Power supply input voltage: 24 VDCPower supply input permissible voltage range: ±5%Power supply input current: 1.3 AElectromagnetic brake type: Power off activated typeElectromagnetic brake power supply: 24 VDC±5% 0.05 A ※1CE marking: affixedNumber of data-select positioning: 64 pointsTeaching pendant: OPX-2AData setting software: MEXE02Mass: motor: 0.3 kgMass: control circuit: 0.17 kgCompatible motor driver:?
