Technical Specifications Flange Dimension: 60 mm square flange Rated Speed: 6000 rpm Rated Torque: 2.0 Nm Rated Voltage: 400 V AC class Encoder Type: Incremental encoder with A/B/Z phase signals Built‑in Brake: None Connector Configuration: 90‑degree rotatable right‑angle circular connectors Protection Class: IP65 Operating Ambient Temperature: ‑20℃ to +40℃ Cooling Method: Natural convection cooling Mounting Form: Flange‑face fastening installation
Functional Features Low‑rotor‑inertia mechanical design achieves ultra‑fast acceleration‑and‑deceleration dynamic response. Incremental encoder outputs A/B/Z differential pulse signals for position‑and‑speed feedback. 90‑degree rotatable right‑angle connectors support adjustment of cable‑exit direction for compact‑machine internal‑wiring layouts. Embedded electronic motor nameplate allows servo drive to read motor‑specific parameters automatically upon power‑on. F‑grade stator‑winding insulation maintains stable thermal performance during frequent high‑cycle start‑stop operations. IP65‑rated housing resists machinery‑internal oil‑mist and dust intrusion. Brake‑free construction minimizes overall axial body length.
Application Scenarios High‑speed light‑duty positioning axes of packaging machinery; pick‑and‑place auxiliary axes; fast‑indexing rotary stations of automated equipment.
Performance Parameters Steady‑state speed‑control accuracy reaches ±0.01 %. Short‑term overload capability achieves 250 % of rated torque. Incremental encoder loses absolute‑position data after power‑off; homing sequence is required at every machine startup. Motor output shaft rotates freely without mechanical locking when power supply is cut off.
Material Composition Die‑cast aluminum‑alloy motor housing, silicon‑steel‑sheet laminated stator core, neodymium‑iron‑boron permanent‑magnet rotor magnets, incremental photoelectric‑encoder assembly, rubber sealing gaskets, alloy‑steel output shaft, rotatable metal circular connectors.
Structural Characteristics 60‑mm compact square mounting flange, output‑shaft manufactured with standard flat‑key slot. Motor rear‑end installs 90‑degree rotatable dual circular connectors, separating motor‑power interface and encoder‑signal interface. No internal brake assembly, overall axial dimension is compact. Full part number VPM02D20AA00 is printed on metal housing nameplate.
Working Principle Servo drive outputs three‑phase variable‑frequency AC power to stator windings to generate rotating magnetic field and drive permanent‑magnet‑rotor rotation. Rear‑end incremental encoder outputs A/B/Z pulse‑train signals, transmits feedback signals back to servo drive for position‑and‑speed closed‑loop calculation. No internal brake mechanism exists; rotor receives no mechanical constraint after power‑off.
Installation Requirements Tighten flange‑mounting screws with torque values strictly complying with specifications printed on motor nameplate. Achieve high‑precision coaxial alignment between motor output shaft and load‑transmission shaft by coupling assembly. Deploy shielded motor‑power cables and shielded encoder‑feedback cables; fully lock circular connectors after mating. Keep encoder‑signal cables physically separated from high‑voltage‑power cables.
Usage Notes External mechanical‑brake assembly must be added separately when motor is applied to vertical‑load mechanical axes. Complete homing procedure at every machine power‑on cycle. Prohibit striking or hammering motor output‑shaft surface. Protect circular connectors against oil‑contamination and moisture ingress. Wear anti‑static wrist straps during maintenance service to avoid electrostatic damage to encoder components.
