Product Description:
Pacific Scientific manufactures the R34JENC-TS-ND-NV-00 servo motor in a square shape design of enclosure that measures 3.25-inches. It belongs to the R34 series and uses rare earth samarium cobalt magnetic configuration to ensure maximum torque output of 14.7 Nm and it delivers a continuous stall torque of 3.0 Nm.
The R34JENC-TS-ND-NV-00 motor integrates a Tachsyn encoder as the primary feedback device for monitoring motion. It lacks a secondary feedback unit but supports various encoders that provides 500 ppr to 1024 ppr feedback. This motor is presented with English shaft and mounting configuration. Its torque constant 0.89 Nm/A to allow efficient torque control and it produces a constant voltage specified at 93 V/Krpm. The R34JENC motor utilizes a continuous stall current of 3.7 A and in overload condition its peak current reaches up to 35 A. The motor’s hot line-to-line resistance is 12.2 Ohms along with cold resistance specified at 8.1 Ohms and an inductance of 30 mH. Its inertia is recorded as 0.000093 kg·m² and its maximum static friction is 0.044 Nm. The R34JENC motor possess a viscous coefficient of 0.010 Nm/Krpm, for stable motion dynamics. Its thermal resistance is 0.76 °C/W and it features a heat dissipation constant of 26 minutes, to ensure temperature stability through its heat sink.
The R34JENC-TS-ND-NV-00 motor lacks a shaft seal but an optional seal can be fitted that requires time to time maintenance to keep the motor protected from external intrudes. It also supports an optional external brake of both 24 or 100 V, with a static holding torque of 3.6 Nm and an inertia value 0.000039 kg·m². This R34JENC motor weighs 3.9 kg without any accessories and it functions up to 302°F of winding temperature due to its class F electrical insulation.
