Product Description:

The 2VM61-020-14 is a Low Inertia Permanent Magnet DC Servomotor. This motor is compact in size and engineered for continuous duty. It belongs to the series of Low Inertia PMDC Servomotors.

The 2VM61-020-14 is designed by Pacific Scientific.

The 2VM61-020-14 is equipped with Class H insulation to withstand extreme temperatures. It operates at 12 or 24 VDC and has a low voltage rating. Compared to winding field devices, the motor has a wider operational speed range. It features revolutionary anti-cog magnets for a smooth low-speed functioning. A durable fused commutator offers a solid electrical connection and minimizes wear. The armature is treated with polyester to boost its strength and service life. Large sealed bearings are included as standard to ensure reliability. The design incorporates brushes with constant force springs and easy field replacement. This Pacific Scientific motor allows for dynamic braking without demagnetization during overcurrent. The rotor is precisely balanced to provide vibration-free low-speed performance. The motor is appropriate for continuous duty operation in industrial applications. In TENV devices, cooling is provided by natural convection, while TEFC versions use an external fan. The conduit box is gasketed, has ample wire space, and features knockout holes for easy access. Mounting choices include NEMA C-face or metric versions with a detachable base. The motor is available in environmentally friendly variants for harsh environments. On select versions, the motor is UL recognized, CSA certified and CE marked.

The Scientific’s 2VM61-020-14 has compact size and high efficiency. It is smaller and lighter than wound field designs while maintaining strength. Long life brushes and sealed bearings reduce service needs. In harsh industrial applications, this motor is built to last and perform consistently. The motor combines efficiency, dependability, and certified compliance in a single package.

Frequently Asked Questions about 2VM61-020-14:

Q: How do constant force brush springs benefit motor performance?

A: They maintain uniform pressure on brushes. This ensures even wear and stable current flow.

Q: Why is polyester impregnation used in the armature of 2VM61-020-14 Motor?

A: Polyester impregnation increases electrical insulation strength. It also enhances mechanical rigidity under heavy duty.

Q: Why is dynamic braking without demagnetization important in 2VM61-020-14 Motor?

A: It enables safe deceleration under overcurrent conditions. The magnets retain strength without performance loss.

Q: What is the purpose of offering NEMA C-face mounting?

A: It allows compatibility with standard industrial gearboxes. This flexibility simplifies integration into automation systems.

Q: How does TEFC cooling in 2VM61-020-14 Motor enhance performance?

A: TEFC design uses an external fan for heat dissipation. This maintains consistent operation under higher continuous loads.
