Page 4: Introduction
Previously, Hudson motors were available for purchase by high volume OEMs exclusively (i.e., companies buying hundreds or thousands of units per year). In late 2020, Teknic opened up sales of Hudson motors to the general public. Hudson motors are among the most reliable, safe, and rugged servo motors available, and our production staff are the guardians of Hudson quality. -

Page 6: Safety And Safe Handling Information
H u d s o n M a n u a l / R e v . 1 . 2 1 Safety and Safe Handling Information General Precautionary Statement Always follow appropriate safety precautions when installing and operating motion control devices. Automated equipment should be designed to prevent personnel from coming into contact with moving parts and electrical contacts that could potentially cause injury or death. -
Page 7: Safe Handling Practices
H u d s o n M a n u a l / R e v . 1 . 2 1 Safe Handling Practices • Do not hammer pulleys, pinions, etc. onto the motor shaft. • Do not wrench or pry pulleys, pinions, etc. off the motor shaft. When removing accessories use a gear puller that pushes on the center of the shaft (offsetting the applied force). -

Page 13: Sine Wave Commutation (Better)
H u d s o n M a n u a l / R e v . 1 . 2 1 During six-step commutation, current flows in only two phases at a time (the odd phase is always off). Example: In Step #1 above, when the commutation sensors read binary (1 0 1) the drive sends current through Phases R and S, while Phase T remains off. - Page 14 H u d s o n M a n u a l / R e v . 1 . 2 1 individual motor phase currents, VTC drives servo control the actual torque produced at the motor shaft. The drive simultaneously takes calibrated current measurements from all motor phases, combines this data with information about rotor position, phase resistance, inductance and back-EMF, and then applies advanced vector mathematics to calculate the exact torque being produced at the shaft.

Page 15: Encoder And Commutation Signals
H u d s o n M a n u a l / R e v . 1 . 2 1 Encoder and Commutation Signals Hudson motors have differential encoder outputs and single-ended commutation (Hall) outputs. Encoder and commutation tracks are optically read from the Hudson encoder disk and then translated to driven signals present at the motor connector. -
Page 16: Encoder Signaling
H u d s o n M a n u a l / R e v . 1 . 2 1 Encoder Signaling Differential encoders on a Hudson motor have balanced, driven outputs intended to drive terminated, twisted pair transmission lines. Differential signals offer excellent common-mode noise immunity and support longer cable runs than single-ended signaling. -
Page 17: Commutation (Hall) Signaling
H u d s o n M a n u a l / R e v . 1 . 2 1 Commutation (Hall) Signaling The optical commutation sensors are 5V TTL, totem pole driven outputs with 10mA maximum current. Commutation Signal and Motor Phase Relaionship The diagram below illustrates the relationship between commutation (Hall) outputs and motor phases for properly wired Hudson motors. -
