The best NEMA 17 high-torque stepper motor depends on the torque required, available space, and whether your driver can supply the motor’s rated current. The YEJMKJ 0.84 Nm models offer the highest listed holding torque; the MAKERELE 73 Ncm option comes as a three-motor set; and the STEPPERONLINE 59 Ncm motor is a shorter-body choice. Compare dimensions and electrical specifications before choosing, because a motor’s holding-torque rating does not by itself predict torque while moving.
| Motor | Listed Holding Torque | Best For |
|---|---|---|
| STEPPERONLINE 48 mm | 59 Ncm | Projects needing a 48 mm body |
| MAKERELE 48 mm | 51 Ncm | Basic single-motor replacement |
| MAKERELE 60 mm, 3-pack | 73 Ncm | Multi-axis builds |
| YEJMKJ 5-pack, 1.5Ω | 0.84 Nm | Several high-torque axes |
| YEJMKJ single, 1.1Ω | 0.84 Nm | One high-torque motor |
STEPPERONLINE 48 mm 59 Ncm Motor
This bipolar NEMA 17 motor is listed with 59 Ncm (about 84 oz-in) holding torque, a 48 mm body, four leads, and a 2 A rating. Its stated dimensions are approximately 42 × 42 × 48 mm, and it includes a 1 m cable and connector.
Best for: 3D printer or CNC projects that need a mid-range torque rating and a 48 mm body. It is selected as a compact alternative to the longer 60 mm motors below. Check the driver’s current setting and the machine’s mounting clearance before ordering. The listing does not provide a full winding-resistance or inductance specification in the supplied details.
MAKERELE 48 mm 51 Ncm Motor
The MAKERELE single motor has a 48 mm body, 1.8-degree step angle, four leads, and a listed holding torque of 51 Ncm (72 oz-in). Its specifications include 1.7 A rated current, 3.4 V rated voltage, 2 Ω phase resistance, and 4.8 mH phase inductance. The shaft is listed as 18 mm long with a 5 mm diameter and D-shaped profile.
Best for: A buyer seeking a single 48 mm NEMA 17 motor with clearly stated winding specifications. Choose it if 51 Ncm is sufficient and its shaft dimensions match the mechanism. It has a lower listed holding torque than the other options here, so it is not the strongest choice when maximum stationary torque is the priority.
MAKERELE Three-Pack, 73 Ncm
This listing includes three 60 mm-body NEMA 17 motors. Each is specified as a two-phase, four-lead motor with a 1.8-degree step angle, 2 A rated current, and 73 Ncm (103 oz-in) holding torque. The listed phase resistance is 1.6 Ω and inductance is 2.1 mH. Each motor weighs 470 g, with a 20 mm shaft length and 5 mm shaft diameter.
Best for: Multi-axis projects that need several matching motors with more listed holding torque than the 48 mm options. It is selected for the combination of a three-motor quantity and 73 Ncm rating. Allow for the 60 mm body length and confirm the driver can be set for the 2 A rating. A three-pack may be unnecessary if only one motor is needed.
YEJMKJ Five-Pack, 0.84 Nm, 1.5Ω
This five-motor set lists 0.84 Nm (118.95 oz-in) holding torque, 2.3 A rated current, 1.5 Ω resistance, and 2.8 mH inductance. The motors have a 1.8-degree step angle, a 42 × 42 × 59.2 mm body, a 24 mm shaft, and a 1 m cable. The listed wire colors are black, green, red, and blue.
Best for: Builders equipping multiple axes who want the highest listed holding torque among these selections. The supplied specifications also give installation-hole spacing and cable details for planning. Check mounting space and driver current capacity. The five-piece quantity is a limitation for anyone replacing only one motor.
YEJMKJ Single Motor, 0.84 Nm, 1.1Ω
This single motor shares the 0.84 Nm (118.95 oz-in) holding-torque rating and 2.3 A rated current of the five-pack option. Its listed body size is 42 × 42 × 59.2 mm, with 1.8-degree steps, a 24 mm shaft, four wires, and a 1 m cable. The stated resistance is 1.1 Ω rather than 1.5 Ω; inductance is 2.8 mH ±20%.
Best for: A project needing one motor with the highest listed holding torque in this comparison. It is selected over the five-pack when a single unit better matches the build. Confirm the winding specification against your driver and control setup; its 1.1 Ω resistance differs from the other YEJMKJ option.
Buying Guide: How to Choose a High-Torque NEMA 17 Motor
How much torque do you need?
Compare holding torque first, but treat it as a stationary specification rather than a guarantee of force at operating speed. Stepper torque can vary with speed and the driver, supply, and system setup. For a demanding motion project, leave room for the load and acceleration needs instead of selecting solely by the largest number.
Will the motor fit your mount and shaft?
NEMA 17 describes the motor’s mounting-frame class, not its body length or shaft details. These options range from 48 mm to roughly 60 mm in body length. Check mounting-hole spacing, overall clearance, shaft diameter and length, and coupling requirements against your design before purchase.
Can your driver handle the current?
Match the driver’s adjustable current range to the motor’s listed rated current: these products range from 1.7 A to 2.3 A. Also review phase resistance and inductance when comparing motors. Do not assume that motors with similar frames or torque ratings use identical electrical settings.
Should you buy a single motor or a set?
A single motor is more appropriate for a one-axis replacement or prototype. A three- or five-pack can suit projects requiring multiple motors, but compare the included quantity with the build plan. For a set, verify that each motor’s listed dimensions and electrical ratings suit every axis.
Frequently Asked Questions
What does NEMA 17 mean?
NEMA 17 identifies a stepper-motor frame size category. It does not specify the motor’s torque, body length, current, or shaft dimensions, so check those details separately.
Which motor listed has the highest holding torque?
Both YEJMKJ options list 0.84 Nm, or 118.95 oz-in, holding torque. One is sold as a five-pack and the other as a single motor.
Is higher holding torque always better?
No. The motor must fit the mount, meet the load requirements, and work with the driver’s current capability. Holding torque also does not describe torque at every operating speed.
Are these motors interchangeable?
Not automatically. Compare body length, shaft dimensions, wiring, rated current, and winding specifications with the existing motor and control system before replacing it.
What does a 1.8-degree step angle indicate?
A 1.8-degree step angle corresponds to 200 full steps per revolution. The control system may use additional step subdivision, but that depends on the driver.
