Accessories and Options for Motors

  • KS corrosion protection and OS surface protection
  • SEW-EURODRIVE offers various optional protective measures which, when combined, provide optimal protection for the operation of motors and gearmotors under special ambient conditions.
  • KS corrosion protection
  • KS corrosion protection for motors comprises the following measures:
    • All retaining screws that are loosened during operation are made of stainless steel.
    • The nameplates are made of stainless steel. Various motor parts are coated with a finishing varnish.
    • Flange contact surfaces and shaft ends are treated with a temporary anti-corrosion agent.
    • Additional measures for brake motors.
  • Surface protection
  • Instead of standard surface protection, motors and gear units are optionally available with OS1, OS2, OS3 or OS4 surface protection.
  • This equips the gearmotors for use in different environmental conditions.

  • On request, SEW-EURODRIVE motors and gearmotors can be supplied with an integrated mechanical brake. The brake is a DC electromagnetic disk brake that is released electrically and applied with spring force. The brake is applied in case of a power failure.
  • It meets the basic safety requirements. The brake can also be released mechanically if equipped with manual brake release. For this purpose, the brake is supplied with either a hand lever with automatic reset or an adjustable setscrew. The brake is controlled with a brake control that is either installed in the motor wiring space or the control cabinet.
Additional options
Plug connector type IS
Optional for DR/DT/DV series AC motors and AC brake motors. The IS plug connector is delivered instead of the standard terminal box. The upper section of the IS plug connector (mating connector) is included in the scope of delivery. The IS plug connector is particularly compact and offers the following connection options:
  • Motor, single-speed or two-pole pole-changing
  • Brake
  • Temperature monitoring (TF or TH)
Attached plug connector type AB / AD / AM
Optional for DR/DT/DV series AC motors and AC brake motors. The attached AB.., AD.., and AM.. plug connector systems are based on the Han Modular® plug connector system made by Harting.
AB.., AD.. and AM.. plug connectors can be used for connecting both single-speed motors and 2-pole pole-changing motors. With brake motors, the brake control system can be either located in the terminal box or in the control cabinet. All versions of the brake control system are possible.
Attached plug connectors type AC / AS
Optional for DR/DT/DV series AC motors and AC brake motors. The attached AC.. and AS.. connector systems are based on the Han 10E/10ES connector system made by Harting.
You can connect both motors with single speed and 2-pole multi-speed motors.
Plug connector type APG
Optional for DT/DV series AC motors and AC brake motors The APG plug connector is based on a plug manufactured by Phoenix Contact and consists of a four-part PlusCon VC. The mating connector is not included in the scope of delivery. The plug connector enables an easily disconnectable hybrid cable connection between the motor / brake motor and a MF.../MM../Z.8A series field distributor with an integrated MOVIMOT® inverter or a suitable third-party decentralized control module.
Attached plug connector type ASK1
Optional for DT/DV series AC motors and AC brake motors The attached ASK1 plug connector system is based on the Han 10ES plug connector system made by Harting. The plug connector is located at the side of the terminal box. The ASK1 plug connector system is used for ECOFAST®-compliant AC motors and AC brake motors.
Carrier plate for ASK1 Optional for DT/DV series AC motors and AC brake motors If you want motor-integrated installation of an ECOFAST®-compliant switchgear or control unit, you require a carrier plate onto which the switchgear or control unit is plugged. The carrier plate can be used regardless of the motor size.
Proximity sensor type NV Optional for DT/DV series AC motors and AC brake motors SEW-EURODRIVE proximity sensors are a simple and inexpensive means of monitoring whether the motor is turning. If a two-track proximity sensor is used, the direction of rotation of the motor can also be detected. Proximity sensors are mounted on the side of the fan guard and so do not increase the length of the motor.
Incremental encoder type EH / ES / EV Optional for DR/DT/DV series AC motors and AC brake motors. SEW-EURODRIVE incremental encoders output 1024 signals/revolution. They have two signal tracks and one index signal track.
Incremental encoders are available as hollow shaft encoders, spreadshaft encoders and solid shaft encoders with coupling. Signal output: TTL or sin/cos.
Encoder mounting device for type ES / EV Optional for DT/DV series AC motors and AC brake motors The motors can be equipped with various encoder attachment fittings for mounting devices from different manufacturers.
Mounting devices for encoders are intended for spreadshaft encoders with an 8 mm (0.3 in) or 10 mm (0.39 in) center bore and for solid shaft encoders (synchronous flange).
Absolute encoder type AV1Y/AV1H SEW-EURODRIVE AV1Y and AV1H absolute encoders are combination encoders. They contain a multi-turn absolute encoder and a high-resolution sinusoidal encoder. You can choose between an SSI interface or a HIPERFACE® interface for data transmission of absolute values. The AV1H absolute encoder has an electronic nameplate.
Forced cooling fan type VR/VS/V DT/DV series AC motors and AC brake motors can be equipped with a forced cooling fan on request. A forced cooling fan is usually not required for mains operated motors in continuous duty. SEW-EURODRIVE recommends a forced cooling fan for the following applications:
  • Drives with high starting frequency
  • Drives with additonal flyweel mass Z (flywheel fan)
  • Inverter drives with a setting range ≥ 1:20
  • Inverter drives that must also generate rated torque at low speeds or even when stationary
Additional flywheel mass Z DR/DT/DV series AC motors and AC brake motors can be equipped with additional flywheel mass Z (flywheel fan) to facilitate smoother starting and braking response from mains-operated motors. The fan gives the motor an additional mass moment of inertia JZ. The flywheel fan replaces the normal fan and does not affect the external dimensions of the motor.
RS backstop DT/DV series AC motors and AC brake motors can be equipped with a backstop if required. The backstop is used for protecting equipment against reverse movement when the motor is switched off.
Canopy C Optional for DR/DT/DV series AC motors and AC brake motors. Liquids and/or solid foreign objects can penetrate the air inlet openings of motors when motors are mounted vertically with their input shaft pointing downwards.
Low noise fan guard Optional for DT/DV series AC motors and AC brake motors. Motor noise is usually amplified by the drive fan guards. The low-noise fan guard reduces the noise level by approximately 3 dB(A) compared to the standard design.
WPU Smooth pole-change unit For DR/DT/DV series multi-speed AC motors and AC brake motors. Normal multi-speed motors cannot switch from high to low speed without jerks unless special measures are taken.
The WPU smooth pole-change unit completes this task electronically and requires minimal wiring expense.
