S6M4H

Product Description:

S6M4H is a Kollmorgen servo motor. It is part of the ServoDisc S-series of compact motors. Options for the motor include encoders, rugged housing, mil-type connectors, and fail-safe brakes. With a flat disc ironless armature, the motor has low weight and delivers exceptional acceleration. Additional motor features include superior speed control, zero cogging and negligible RFI. Specifications for the motor tachometer include 0.75 Volts/KRPM output voltage, 1000 Ohms minimum load resistance, 0.06% linearity of output voltage, and 1.5% maximum peak-to-peak ripple. Peak torque output of the S6M4H servo motor is 151 N-cm. Additional performance specifications include 3000 RPM>. rated speed, 15 N-cm continuous torque at 25 degrees, 13 N-cm rated torque at 40 degrees Celsius, 6000 RPM maximum recommended speed, 0 oz-in cogging torque and 14 N-cm continuous stall torque.

Electrical specifications for the S6M4H motor include 17.7 volts rated terminal voltage, 5.20 Amps rated continuous current, 51 Amps peak current and 4.8 Amps continuous stall current. Winding on the motor has a 1.207 Ohms terminal resistance and 0.940 armature resistance. Back EMF constant for the winding is 3.15 V/KRPM. Torque constant of the motor is 3.01 N-cm/Amp and the viscous damping constant is 0.1 N-cm/KRPM. Inductance of the servo motor winding is less than 100 microhenry. The temperature coefficient of KE is 0.02 % per degrees Celsius rise. There are 82 commutator bars on the motor winding. Moment of inertia of the motor is 0.060 kg m2. The static friction torque is 0.6 N-cm. Mechanical dimensions of the compact servo motor include <<0.95 kilograms weight, 3.39 inches diameter and 1.61 inches length. The motor carries high voltages and current and should be handled by trained personnel.
