BRS3 1 Introduction 1 Introduction 1.1 Motor family 1 The motors are 3-phase stepper motors with a very high power density. They carry out precise step-by-step movements that are controlled by a drive. The 3-phase stepper motors are accurate, powerful and sturdy and excel with a high power density. Due to the high holding torque, a gearbox is not required in most cases. Sine commutation allows for almost fully resonance-free operation of the motor.
1 Introduction 1.2 BRS3 Options, accessories and cables The motors are optionally available with: • Encoder • Holding brake • Connector • Various degrees of protection For the options, see the technical data in the various motor descriptions. The following accessories are available: • Holding brake controller HBC • Cables • Gearbox 0198441113730, V2.02, 03.2011 See chapter 7 "Accessories and spare parts" for pre-assembled motor cables and encoder cables for the drive systems.
