Specifications:
The GR Series motors are available in three sizes: GR12, GR16, and GR19. They offer power ratings from 420 to 1000 Watts, peak torque from 1334 to 3200 Ncm, and continuous torque from 133.4 to 320 Ncm. The motors operate at speeds up to 6000 RPM and voltages ranging from 64 to 129 Volts, with continuous stall currents between 5.0 and 8.6 Amps.

General Benefits:
The GR Series motors provide high peak torque output, zero cogging, low inertia, rapid acceleration, and stability at high temperatures. They feature long brush life and are controllable with servo amplifiers. Design options include custom shafts, encoders, tachometers, gearboxes, and pulleys.

Applications:
These motors are suitable for servo mechanisms, motion control, industrial robots, CNC machining, printing machinery, logistics solutions, medical mobility, medical scanners, flight simulators, marine autopilots, high ambient temperature ventilation, valve actuators, and scientific instrumentation.

Markets:
The GR Series serves industrial automation, medical, life sciences, aerospace & defense, printing, logistics, instrumentation, test and measurement, oil & gas, and offshore marine sectors.

Design Modifications:
Options include encoders, customized shafts, timing pulleys, EMC suppression, tacho output voltage, connectors, tri-rated cable, operation in 150°C ambient, US mounting configuration, and protective covers.

Standard Tacho Option:
All models have a motor output voltage gradient of 3 V/KRPM with a tolerance of +5% to -0% and a voltage ripple of 5%. Rotor inertia is 350 g/cm².
