Product Description:
The DBL2H00040-0R2-000-S40 is a brushless servo motor produced by Kollmorgen for the DBL Synchronous Servomotors series. Designed with a standard-length housing, this motor is intended for closed-loop motion axes where compact size and rapid acceleration are important. In an automation cell, it converts drive current into precise torque while resolver feedback keeps the controller synchronized with the rotor position. The motor uses plug-in connectors for its electrical connections. Its cables exit at an angle toward the B-side, which helps simplify wire routing in confined machine spaces and control panels.
The motor attaches through a 55 mm square flange, providing a compact mounting interface for compatible machine frames and drive assemblies. Its enclosure has an IP54 protection rating, which limits dust ingress and protects internal components against splashing water. Rotor position is measured by a resolver, which maintains a reliable phase reference at elevated temperatures. A two-pole electromagnetic layout supports high base speeds while helping reduce cogging during controlled rotation. Internally, the stator uses a high-speed winding that reduces inductive reactance and permits higher fundamental frequencies from the drive. Contact protection at the feedback connection helps prevent accidental contact with conductive parts. Plug-in power and feedback connectors also reduce the amount of internal wiring required during installation.
The motor supports an ambient operating temperature of +5 to +40 °C, making it suitable for typical indoor production environments. It can operate at a maximum relative humidity of 95% when condensation is prevented. The output end uses a smooth shaft, so torque is transferred through a clamping or interference-fit coupling rather than a keyed connection. This shaft arrangement can provide uniform coupling contact when the mating component is installed correctly. Because the motor is supplied without a holding brake, machinery that must retain a vertical or suspended load at standstill must use drive-applied torque or a separate mechanical locking device. The angled B-side cable orientation provides additional routing flexibility where clearance behind the motor is limited.
