Product Description

YEJ Series DC Brake Motor – Reliable Electromagnetic Braking for Industrial Applications

Raydafon Group offers the YEJ series – a comprehensive range of three‑phase asynchronous motors with integrated DC electromagnetic brakes. Designed for applications requiring rapid stopping, precise positioning, and holding torque, these motors combine high efficiency with robust construction. Available in 2‑pole, 4‑pole, and 6‑pole configurations with power ratings from 0.12 kW up to 22 kW, the YEJ series delivers reliable performance for hoists, conveyors, gate operators, and industrial automation.

Key Features at a Glance

High Braking Torque: Fast response and reliable holding torque for safety-critical applications.
Wide Power Range: 0.12 – 22 kW, with speeds of 3000, 1500, and 1000 rpm (2/4/6 pole).
Energy Efficient: Meets IE2/IE3 efficiency levels, reducing operating costs.
IP55 Protection & F‑Class Insulation: Suitable for dusty and wet environments.
Robust Construction: Cast iron or aluminium housing with enhanced heat dissipation.
Customisable: Special voltages, frequencies, brake voltages, and mounting arrangements available.

Electromagnetic DC BrakeIntegral brake engages on power loss – provides rapid stopping (0.1‑0.3s no‑load) and static holding torque up to 200 Nm.

High Efficiency MotorOptimised design meets GB18613‑2012 and IEC efficiency standards, minimising energy consumption.

Versatile MountingAvailable in B3 (foot), B5 (flange), B14 (face), and B35 (foot+flange) configurations to suit any drive layout.

Low Noise & VibrationPrecision‑balanced rotor and high‑quality bearings ensure smooth, quiet operation.

Durable ConstructionCast iron frame (larger sizes) or aluminium housing (smaller sizes) with IP55 protection – resists rust and corrosion.

Easy IntegrationStandard IEC frame sizes and shaft dimensions allow direct replacement of existing brake motors.

Frequently Asked Questions

Q: What is the brake supply voltage for YEJ motors?

A: For frame H≤100, brake supply is AC220V (rectified DC99V); for H≥112, it is AC380V (rectified DC170V). Other voltages can be customised.

Q: How fast does the brake engage?

A: The no‑load braking time ranges from 0.10 to 0.30 seconds depending on frame size and inertia.

Q: Can I use the motor in a vertical mounting position?

A: Yes, we offer special brake configurations and bearing arrangements for vertical (shaft‑up or shaft‑down) applications.

Q: Are these motors suitable for frequent start‑stop cycles?

A: Yes, the YEJ series is designed for S1 duty with intermittent braking, but we can also provide S4/S5 duty ratings upon request.

Q: What is the warranty period?

A: We offer an 18‑month warranty from shipment date, covering manufacturing defects, with full technical support.
