(2) In this Chapter and Schedules 16 to 18—

“brake motor” means a motor equipped with an electromechanical brake unit operating directly on the motor shaft without couplings;

“continuous duty operation” means capable of continuous operation at a rated power with a temperature rise within the specified insulation temperature class, specified as specific duty types S1, S3 >=80 per cent or S6 >=80 per cent;

“cordless or battery operated equipment” means an appliance deriving its energy from batteries;

“declared values” means the values provided by the manufacturer, importer or authorised representative for the stated, calculated or measured technical parameters in the technical documentation, in accordance with the conformity assessment procedure referred to in regulation 35;

“drive with sinusoidal input current” means a VSD with a sinusoidal waveform of the input current, characterised by a Total Harmonic Content below 10 per cent;

“electric motor” or “motor” means a device that converts electrical input power into mechanical output power in the form of a rotation with a rotational speed and torque that depends on factors including the frequency of the supply voltage and number of poles of the motor;

“Ex eb increased safety motor” means a motor intended for use in explosive atmospheres and certified “Ex eb”, as specified in British Standard BS EN 60079, and

“other explosion-protected motor” means a motor intended for use in explosive atmospheres and certified “Ex ec”, “Ex tb”, “Ex tc”, “Ex db”, or “Ex dc” as specified in British Standard BS EN 60079;

“energy efficiency” of a motor means the ratio of its mechanical output power to the electrical active input power;

“equivalent model” means a model which has the same technical characteristics relevant for the technical information to be provided, but which is placed on the market or put into service by the same manufacturer, importer or authorised representative as another model with a different model identifier;

“factory acceptance test” means a test on an ordered product where the customer uses witnessed testing to verify the product’s full accordance with contractual requirements, before the product is accepted or put into service;

“hand-held equipment” means a portable appliance intended to be held in the hand during normal use;

“hand-guided equipment” means a non-road mobile appliance that is moved and guided by the user during normal use;

“mains” or “electric mains” means the electricity supply from the electricity grid;

“model identifier” means the code, usually alphanumeric, which distinguishes a specific product model from other models with the same trade mark or the same manufacturer’s, importer’s or authorised representative’s name;

“motor with mechanical commutators” means a motor in which a mechanical device reverses the direction of the current;

“phase” means the type of configuration of the mains;

“pole” means a north or a south pole produced by the rotating magnetic field of the motor, whose total number of poles determines its base speed;

“regenerative drive” means a VSD that is able to regenerate energy from the load to the mains, and which induces a 180° +/- 20° phase shift of the input current to the input voltage when the load motor is braking;

“test load” of a VSD means the electrical device used for testing purposes that determines the output current and the output displacement factor cos phi;

“totally enclosed non-ventilated motor” means a motor designed and specified to operate without a fan, and which dissipates heat predominantly through natural ventilation or radiation on the totally enclosed motor surface;

“variable speed drive” or “VSD” means an electronic power converter that continuously adapts the electrical power supplied to a single motor to control the motor’s mechanical power output, according to the torque-speed characteristic of the load driven by the motor, by adjusting the power supply to a variable frequency and voltage supplied to the motor, and includes all integrated protection devices and auxiliaries;

“witnessed testing” means actively observing the physical testing of the product under investigation by another party, to draw conclusions on the validity of the test and the test results. This may include conclusions on the compliance of testing and calculations methods used.
